+title: "Agents context management"
+---
+<PlanAvailability slug="all-commercial" />
+
+Mattermost Agents are designed to handle context efficiently, ensuring that only necessary information is sent to the Large Language Model (LLM) for generating accurate responses. This document outlines how Agents process and include relevant context. The company name, the server name, and the time are always passed to the LLM to ensure accurate and contextually relevant responses.
+
+<Note>
+
+**Ensure data privacy**
+
+We recommend that customers with strict privacy requirements run the LLM locally to prevent sensitive data, including personally identifiable information (PII) and message content, from being shared with an external LLM hosting vendor. This ensures data privacy while enabling Agent functionality.
+
+</Note>
+
+## Direct messages to Agent bots
+
+When you send a direct message to an Agent bot, the context sent to the LLM includes:
+
+- The profile information of the user sending the prompt.
+- Chat messages exchanged between the user and the bot.
+
+**Additional context in direct messages**
+
+By default, some tool use is enabled to allow for features such as integrations with JIRA, and additional context may be sent to the LLM, depending on the prompt that includes:
+
+- Jira tickets (public tickets)
+  - Example: Summarize the Jira ticket: \<LINK TO TICKET\>
+- GitHub issues
+  - Example: Summarize the GitHub issue: \<LINK TO ISSUE\>
+- User data
+  - Example: What is @Bob's position?
+
+## @-Mentions in channels
+
+When you `@mention` Agents in a channel, the context sent to the LLM includes:
+
+**Standalone messages (@-mentions in a channel)**
+
+- The message containing the @-mention, including any attachments.
+- The channel name and display name.
+- The team name and display name.
+- The profile information of the user sending the prompt.
+
+**Threaded messages (@-mentions in a thread)**
+
+- Everything sent when used in a standalone message.
+- Messages within the thread, including the usernames of the users involved, as well as any attachments and their filenames.
+
+**Context differences between standalone and threaded messages:**
+
+- For @-mentions in standalone messages, the context includes only the mentioned message.
+- For @-mentions in threads, the entire thread's messages are included, along with usernames of the authors of the messages.
+
+## Built-in ways to trigger Agents
+
+In addition to regular chat interactions, Agents provide specialized features where extra context is sent to the LLM. Each feature provides specialized context tailored to the task being performed. Below are the scenarios where extra context is sent to the LLM:
+
+- **Thread summarization**: Includes thread messages and the usernames of the authors
+- **Meeting summary**: Incorporates transcriptions from calls
+- **Channel summary since last visit**: Uses channel posts along with their authors to create summaries.
+- **Finding action items & open questions**: Analyzes thread and channel messages to identify action items or open questions.

+title: "Auto-translate messages"
+---
+<PlanAvailability slug="ent-adv" />
+
+From Mattermost v11.5, messages in channels with auto-translation enabled are automatically translated into your preferred language. This enables seamless multilingual collaboration — you can read and respond in your own language while teammates do the same in theirs.
+
+## How auto-translation works
+
+Your system admin must first [enable auto-translation](/administration-guide/manage/admin/autotranslation) for your Mattermost instance. Then, a system admin or channel admin can enable it for individual channels. When autotranslation is enabled in a channel:
+
+- The language of each message is automatically detected.
+- Messages are translated into your preferred display language and shown in place of the original text.
+- Code blocks, URLs, and @mentions are preserved and not translated.
+- Translations happen asynchronously — there may be a brief delay before the translated text appears.
+- Messages written in your preferred language are not translated.
+
+## View translated messages
+
+Translated messages display in place of the original text. To view the original untranslated message, select the **translation** icon on the message.
+
+## Set your preferred language
+
+Auto-translation translates messages into your Mattermost display language. To change your display language:
+
+1.  Select the gear icon to open **Settings**.
+2.  Select **Display \> Language**.
+3.  Choose your preferred language.
+4.  Select **Save**.
+
+See the [language](/end-user-guide/preferences/manage-your-display-options#language) documentation for more details.
+
+## Opt out of auto-translation in a channel
+
+You can opt out of auto-translation on a per-channel basis if you prefer to see original messages in a specific channel. To opt out:
+
+1.  Open the channel where you want to disable auto-translation.
+2.  Select the channel name at the top to open the channel menu.
+3.  Disable the auto-translation option for this channel.
+
+You'll see original, untranslated messages in that channel going forward. You can re-enable auto-translation at any time using the same steps.
+
+## Limitations
+
+- **Direct and group messages**: Your system admin may have restricted auto-translation in direct and group messages. If auto-translation isn't available in a direct or group message, contact your system admin.
+- **Short or mixed-language messages**: Very short messages or messages that mix multiple languages may not be reliably detected and translated.
+- **Code-only messages**: Messages that contain only code blocks are not translated, as code is preserved in its original form.
+- **Translation accuracy**: Translation quality depends on the translation provider configured by your system admin. Some languages or specialized terminology may produce less accurate results.

+<PlanAvailability slug="all-commercial" />
+
+All organizations are different and have different communication needs. The importance of organizing your conversations increases as your user base grows. The following are ideas for how you might want to name, group, and structure your channels. If you change your mind about a channel's name, you can [rename it](/end-user-guide/collaborate/rename-channels).
+
+## Basic structure
+
+- Channel names appear in menus where users select which conversations to join.
+- Channel names are unique.
+- Channel names have a 64-character limit to ensure readability on both desktop and mobile devices.
+- An additional 1024 characters are available for describing the channel's focus in the channel header and channel information pane.
+- An additional 128 characters are available for a **Channel Purpose** that's visible in the channel header and the channel information pane.
+- Channel names can include standard Unicode emojis that are universally supported emojis that look the same (or similar) across platforms. Specify a Unicode emoji by positioning your cursor in the channel **Display Name** field and accessing the Unicode emoji picker for your operating system, as follows:
+
+> - On Windows press <kbd>Windows</kbd> + <kbd>.</kbd> or <kbd>;</kbd> to open the Unicode emoji picker.
+> - On macOS, press <kbd>Ctrl</kbd> + <kbd>⌘</kbd> + <kbd>Space</kbd> to open the Unicode emoji picker.
+
+We recommend prefixing channel names with emojis for the following reasons:
+
+> - Emojis can make it easier for users to quickly identify and manage channels, particularly in large workspaces with many channels.
+> - Sharing the same emoji across channels related to a specific category or function helps maintain organization and consistency across the workspace.
+> - Making channels more visually distinct with emojis helps users find the channels they need more quickly and easily at a glance, reducing the time spent searching for the right channel.
+> - New users can quickly understand the purpose of various channels based on their emoji prefixes without needing extensive explanations.
+> - As users grasp channel structure through emojis, the time and effort needed to train new members on navigating the workspace is reduced.
+> - A well-organized and visually appealing workspace can encourage users to participate more actively, which can lead to more effective communication and collaboration.
+
+## Scope channel names
+
+It's natural to start with broadly defined channels and let them divide into narrower topics as discussions progress.
+
+For example, you might begin with a general "Marketing" channel. As conversations progress, you might divide that channel into: "Marketing: Website", "Marketing: Social Media", "Marketing: General".
+
+<Tip>
+
+Use colons to separate sections of channel names, rather than `-` or `>` which require more spaces to display.
+
+</Tip>
+
+As the organization grows, disciplines might split across business units, products and geographies, with channel names like "US: Marketing" and "UK: Marketing".
+
+<Tip>
+
+If you need to shorten country names, use standard [2-letter country codes](https://www.nationsonline.org/oneworld/country_code_list.htm).
+
+</Tip>
+
+You can combine the hierarchies, with formats like `[SUB-TEAM]: [TOPIC]: [SUB-TOPIC]`. For example: `US: Mrkt: Website` and `UK: Mrkt: Social Media`.
+
+<Tip>
+
+Shorten words, particularly categories, by removing vowels, endings, and redundant letter sounds. Example: Turn "Marketing" into "Mrkt", and "Project" into "Prjt".
+
+</Tip>
+
+Good naming can take a team up to several thousand channels without significant confusion. Eventually every organization hits a limit and an additional team might need to be created on the server to accommodate the large number of channels. Keeping names clear and short lets users navigate large collections of channels quickly.
+
+Here are different navigation options and types of channels to consider.
+
+### Navigate channels using the keyboard
+
+Keyboard shortcuts allow users to jump between channels. See the [keyboard shortcuts](/end-user-guide/collaborate/keyboard-shortcuts) documentation for all available keyboard shortcuts.
+
+### Topic channels
+
+Topics are broad categories for organizing discussions. Topics are similar to how a user might create a folder for organizing emails or documents. Examples: Recruiting, Interviews, Legal Reviews, Documentation.
+
+Users can join and leave topic-based channels, as well as add colleagues to have topic-based discussions.
+
+As teams get larger and the number of channels increase, you may start naming topics in a hierarchy to make them easier to find. Examples: Legal: Trademarks, Legal: Contracts, Legal: Licensing.
+
+### Meeting channels
+
+Meeting channels are often used to organize regular meetings. Members can add topics as messages to be discussed during the regular meeting time. Examples: Monday Sales Update, All Hands Meeting.
+
+There are three built-in features to make meetings easier:
+
+1.  Numbered agenda items in title text
+
+You can number and format messages as agenda items to discuss for the next meeting.
+
+<Tip>
+
+Try pasting the following as an example in a channel designated for meetings:
+
+    #### 1) Agenda item example
+        #### Commentary about agenda item to be discussed.

+
+2.  Threaded messaging
+
+On an agenda item message, you can select `[...] > Reply` to leave comments about an agenda item before or after a meeting to extended discussion.
+
+3.  Header links
+
+When meeting remotely, add persistent links to your video or audio conferencing solution, like Zoom, Google Hangouts, or BlueJeans in the channel header. See our [documentation](/end-user-guide/collaborate/channel-header-purpose) to learn more about working with channel headers.
+
+When it's time to meet, your team can select the conference link to connect.
+
+### Sub-team channels
+
+Sub-teams can include people from the same discipline, project teams, people with the same manager or other groups brought together for a shared purpose. Examples: Developers, Marketers, Offsite Organizing Committee, SusanK's Directs
+
+As sub-teams grow beyond a manageable size for one channel, they can sub-divide. Examples: US: Developers, UK: Developers, SusanK's Directs, SusanK's Extended Directs.
+
+### Project channels
+
+Project channels discuss how groups of people come together to achieve specific outcomes. Examples: Logo Design, Localization, Product Launch.
+
+Projects are often private channels rather than public channels and are used to organize a small team around a project brought up in a larger channel. The Project Channel is used to do detailed work, and updates are typically communicated back to larger channels.
+
+### Location channels
+
+If your teams are in different buildings, cities or regions, you can create Location channels to help people coordinate meetings and get-togethers. Examples: Building 10, Palo Alto, Toronto, Delaware.
+
+This helps share announcements and discussions relevant to only those locations.
+
+### Data channels
+
+Data channels allow automatic integration. Information like new or updated support tickets or bug reports, Twitter updates or mentions of your company name in the news can all be made available in channels your team chooses to monitor. There is a wide array of options. Examples: Bugs, Support Tickets, Twitter, News Mentions.
+
+People might use these channels like a daily newspaper, reading about everything that's happened in the last day, while other configurations allow notifications to alert only when their username or certain key words are mentioned.
+
+## Channel naming examples
+
+Here is an example of what a marketer's channels might look like in a small team:
+
+CHANNELS
+
+- Recruiting
+- Interviews
+- Marketing
+- Sales
+- All Hands Meeting
+- Town Square
+- Off-Topic
+
+PRIVATE CHANNELS
+
+- Website
+- Twitter Marketing
+- Logo Design
+
+DIRECT MESSAGES
+
+- \[Sales People\]
+- \[Marketers\]

+
+Here's an example of what a marketer's channels might look like if she was working in the Palo Alto, California office of a large enterprise, working on a product called "Pontoon":
+
+CHANNELS
+
+- Geo: PA: Recruiting

+Channels are used to organize conversations across different topics. The channels you're a member of display in the left pane. Learn how to create channels by visiting the [create channels](/end-user-guide/collaborate/create-channels) documentation.
+
+There are 5 types of channels in Mattermost:
+
+- [Public channels](#public-channels)
+- [Private channels](#private-channels)
+- [Direct message channels](#direct-message-channels)
+- [Group message channels](#group-message-channels)
+- [Archived channels](#archived-channels)
+
+<Tip>
+
+Enterprise customers can additionally configure [read-only](/administration-guide/onboard/advanced-permissions#read-only-channels) broadcast channels.
+
+</Tip>
+
+## Public channels
+
+Public channels are open to everyone on a team and are identified with a **Globe** <img src={useBaseUrl('/img/ui/globe_E805.svg')} alt="Public channels are identified with a Globe icon." className="theme-icon" /> icon. New team members are automatically added to the **Town Square** channel.
+
+See the [Join and leave channels](/end-user-guide/collaborate/join-leave-channels) documentation for details on discovering, joining, and leaving other channels.
+
+## Private channels
+
+Private channels are channels for sensitive topics and are only visible to selected team members. Private channels are identified with a **Lock** <img src={useBaseUrl('/img/ui/lock-outline_F0341.svg')} alt="Private channels are identified with a Lock icon." className="theme-icon" /> icon. Channel members can choose to leave private channels at any time.
+
+<Note>
+
+- Mattermost Enterprise and Professional customers can restrict channel management to system and channel admins.
+- In a Mattermost Team Edition instance, any member of a private channel can add or remove other members from private channels.
+
+</Note>
+
+## Direct message channels
+
+Direct message channels are for conversations between 2 people. Only members of the conversation can see direct messages and channel heading information, including the last active status of the other user.
+
+You can start a direct message with people on other teams [unless the system admin has disabled your ability to do so](/administration-guide/configure/site-configuration-settings#enable-users-to-open-direct-message-channels-with).
+
+Direct messages update the numbered badge count and trigger a notification unless the direct message is muted, or your notifications are disabled. See the [notification documentation](/end-user-guide/preferences/manage-your-notifications) for details on customizing notifications based on your preferences.
+
+<Note>
+
+- From Mattermost v10, when sending a direct message, Mattermost warns you that the recipient's availability is set to [Do Not Disturb](/end-user-guide/preferences/set-your-status-availability#set-your-availability), and when the recipient's local time is outside of regular business hours (between 10PM and 6AM). This warning displays directly above the message text field.
+- When a Mattermost user is deactivated in the system, your [direct message channel](/end-user-guide/collaborate/channel-types#direct-message-channels) with that user are [archived](#archived-channels) and marked as read-only. An **Archived** icon <img src={useBaseUrl('/img/ui/archive-outline_F120E.svg')} alt="Archived channels are identified with a File Box icon." className="theme-icon" /> displays next to archived channels.
+
+</Note>
+
+## Group message channels
+
+Group message channels are for conversations between 3 to 7 people. Only members of the conversation can see group messages. Group messages always display a new message badge.
+
+Want to have a group conversation with more than 7 people? [Create a private channel](/end-user-guide/collaborate/create-channels). Alternatively, from Mattermost v9.1, you can [convert group messages to a private channel](/end-user-guide/collaborate/convert-group-messages).
+
+<Note>
+
+- You can start a group message with people on other teams when [unless the system admin has disabled your ability to do so](/administration-guide/configure/site-configuration-settings#enable-users-to-open-direct-message-channels-with).
+- From Mattermost v9.1, group messages increase the numbered badge count and trigger a notification unless the direct message is muted, or your notifications are disabled. Control how you're notified about group message conversations by going to **Settings \> Notifications**. See the [notification documentation](/end-user-guide/preferences/manage-your-notifications) to learn more.
+- Any group message history you have with a deactivated user remains available [unless your system admin disables your ability to do so](/administration-guide/configure/site-configuration-settings#allow-users-to-view-archived-channels).
+
+</Note>
+
+## Archived channels
+
+Archived channels are deactivated public, private, direct message, or group message channels that are no longer used. Archived channels are identified with a **File Box** <img src={useBaseUrl('/img/ui/archive-outline_F120E.svg')} alt="Archived channels are identified with a File Box icon." className="theme-icon" /> icon. From Mattermost v11.5, archived private channels are identified with a distinct **Archive Lock** icon to visually differentiate them from archived public channels.
+
+[Archiving a channel](/end-user-guide/collaborate/archive-unarchive-channels#archive-a-channel) marks it read-only to prevent new messages from being sent and preserve channel history. You can continue to access archived channels, unless your system admin has [disabled](/administration-guide/configure/site-configuration-settings#allow-users-to-view-archived-channels) your ability to do so.

+The Mattermost for Microsoft Teams integration enables you to break through siloes in a mixed Mattermost and Teams environment by forwarding real-time chat notifications from Teams to Mattermost.
+
+![Mattermost for Microsoft Teams integration forwards real-time chat notifications from Teams to Mattermost.](/images/microsoft-teams-chat-notifications.gif)
+
+<PlanAvailability slug="academy-msteams" />
+
+## Connect your Mattermost account to your Microsoft Teams account
+
+<Note>
+
+Your System Administrator must install and enable the [Mattermost for Microsoft Teams integration](/integrations-guide/microsoft-teams-sync) and ensure [support for notifications is enabled](/administration-guide/configure/plugins-configuration-settings#sync-notifications) in order for you to connect your account and recieve chat notifications.
+
+</Note>
+
+Once the integration is installed and configured by a System Administrator, you can connect your Mattermost user account to your Microsoft Teams account. You only need to complete this step once.
+
+1.  Log into Mattermost using your credentials.
+2.  In any channel, run the `/msteams connect` slash command, and select the resulting link.
+3.  Authenticate with Microsoft Teams using the email address matching your account in Mattermost.
+
+Mattermost will confirm when your account is connected.
+
+Once you've connected your Mattermost account to your Microsoft Teams account, when you're offline or away from Microsoft Teams, any messages you receive in a chat or group chat in Microsoft Teams will display in Mattermost as a notification and include a link to open the chat in Microsoft Teams to continue the conversation. These notifications won't appear if you've been recently active in Teams.
+
+![An example of a chat message notification.](/images/microsoft-teams-chat-notifications.png)
+
+### Manage notification settings
+
+Manage your Mattermost notification settings for the Microsoft Teams integration at any time in **Settings** \> **Plugin Preferences**
+
+![Manage notification settings for the Microsoft Teams integration in Account Settings \> Plugin Preferences](/images/teams_plugin_notification_settings.png)
+
+<Tip>
+
+You can run the following [slash commands](/integrations-guide/run-slash-commands) to manage your integration settings by typing the commands into the Mattermost message text box, and selecting **Send**:
+
+- `/msteams connect`: Connect your Mattermost account to Microsoft Teams account.
+- `/msteams disconnect`: Disconnect your Mattermost account from Microsoft Teams account.
+- `/msteams status`: Show your current connection status.
+- `/msteams notifications on|off`: Change your current notifications settings.
+
+</Tip>
+
+## Frequently asked questions
+
+### How does the integration determine when to send chat notifications?
+
+Chat notifications are sent in real-time whenever you're not active in Microsoft Teams and receive a chat or group chat. Mattermost uses your online status in Teams to determine if a chat notification should be delivered. Mattermost delivers notifications if you appear **Away** or **Offline** in Microsoft Teams, so the default behavior for when notifications will be delivered depends on the client you typically use to access Microsoft Teams:
+
+- Web browser: Mattermost delivers notifications when you've not had activity in your Microsoft Teams browser tab for 5 minutes or more, when the browser tab is closed, or when you mark yourself as **Offline** in Microsoft Teams.
+- Desktop app: Mattermost delivers notifications when you've not had activity at your computer for 5 minutes or more, when the Microsoft Teams desktop app is closed, or when you mark yourself as **Offline** in Microsoft Teams.
+
+In order to avoid double notifications, Mattermost won't deliver chat notifications when your availability is set to **Available**, **Busy**, **Do not disturb**, or **Be right back** in Microsoft Teams.

+
+Due to potential security concerns with sharing private channel history, only system admins can convert private channels to public channels using the System Console.
+
+<Note>
+
+- The ability to convert private channels to public channels using the [API](https://api.mattermost.com/#tag/channels/operation/UpdateChannelPrivacy) or [mmctl channel modify command](/administration-guide/manage/mmctl-command-line-tool#mmctl-channel-modify) is limited to system admins, team admins, and users with specific granular admin roles. Team admins have this permission by default, but system admins can restrict it or assign it to other roles.
+- Granular roles require permissions for managing User Management Channels and Groups, including `sysconsole_write_user_management_channels` and `sysconsole_write_user_management_groups`. Manage permissions through the [permission scheme](/administration-guide/onboard/advanced-permissions#permissions-structure).
+- If [Sync Group channel management](/administration-guide/manage/team-channel-members#channel-management) is enabled, private channels can't be converted to public channels.
+
+</Note>
+
+1.  Go to **System Console \> Channels**.

+5.  (Optional) Assign the channel to a category. When [channel category sorting](/administration-guide/configure/experimental-configuration-settings#enable-channel-category-sorting) is enabled (the default from Mattermost v11.8), channel admins see a **Default category (optional)** field when creating or editing a channel. You can select an existing category, type a new category name, or clear the default category from channel settings. Members who join the channel see it under that category in their sidebar. If this option isn't available, you can [customize your channel sidebar](/end-user-guide/preferences/customize-your-channel-sidebar).

+
+Automatic actions include:
+
+- Displaying a temporary welcome message for new channel members.
+- Automatically adding the channel to a [category in the user's channel sidebar](/end-user-guide/preferences/customize-your-channel-sidebar).
+- Prompting to run a playbook based on the contents of a message.

+---
+<PlanAvailability slug="entry-adv" />
+
+From Mattermost v10.9, users with admin permissions can enable channel banners to remind channel members about being diligent to avoid data spillage in channels that aren't intended for classified or sensitive information. These non-dismissible banners can be styled using Markdown and are visible across all Mattermost clients, including web browsers, the desktop app, and the mobile app.
+
+Channel banner use cases include the following:
+
+- Security classifications, such as **SENSITIVE INFORMATION: IMPACT LEVEL 5** with a distinctive color to alert members of the required security level.
+- Important notices, such as **Reminder: Code complete deadlines are Fridays at 3 PM**, for recurring reminders.
+- Policy or terms, such as **All discussion in this channel is private and restricted** with a red color to signal caution.
+
+Mattermost [channel admins](/end-user-guide/collaborate/learn-about-roles#channel-admin), [team admins](/end-user-guide/collaborate/learn-about-roles#team-admin), and [system admins](/end-user-guide/collaborate/learn-about-roles#system-admin) can enable a banner with custom text at the top of Mattermost public or private channels.
+
+Create a channel banner:
+
+1.  Open a channel where you have administrative permissions.
+2.  Select the channel name at the top of the center pane to access the drop-down menu, then select **Channel Settings**.
+3.  Select **Configuration** and enable the **Channel Banner** option.
+4.  Specify the banner text you want to display at the top of the channel. You can style the text using [Markdown](/end-user-guide/collaborate/format-messages#use-markdown), if desired.
+5.  Select the banner color.
+6.  Select **Save** to apply the changes. The banner displays immediately.
+
+## Change a channel banner
+
+You can change the banner text or color at any time by following the same steps above. The new banner text or color displays immediately.
+
+## Remove a channel banner
+
+Disable the **Channel Banner** option in the channel settings to remove the banner from the channel.
+
+<Tip>
+
+System admins can grant any user the ability to create and manage channel banners by assigning the **Manage Channel Banners** permission in the System Console. See the [advanced permissions](/administration-guide/onboard/advanced-permissions) documentation for details.
+
+</Tip>
+
+## Classification markings
+
+From Mattermost v11.8, system admins can configure classification markings that display as global or channel-level banners in the web and desktop apps. See the [Classification Markings](/administration-guide/configure/site-configuration-settings#classification-markings) configuration documentation for setup details.
+
+Classification markings use predefined or custom classification levels, including the classification name and banner color. These markings are informational only and don't control access to channels, messages, files, or other Mattermost resources.
+
+When a channel classification is applied, Mattermost displays the selected classification as the channel banner. Classification markings take priority over a custom channel banner when both are configured for the same channel.

+
+Every Mattermost user contributes to data security. From Mattermost v11.1, you can help keep your workspace secure and prevent data spillage by quarantining messages that may contain sensitive or restricted information for review by authorized moderators. Your quick actions can prevent accidental leaks before they spread, and build a culture of shared responsibility for secure communication.
+
+## Quarantine a message
+
+For example, you notice a public post in a channel that contains internal project details that not all users should have access to. You can quarantine that message as **Sensitive data** to alert designated content reviewers right away.
+
+<Note>
+
+You can only quarantine messages posted in public or private channels. The **Quarantine for Review** action isn't available in direct messages or group messages.
+
+</Note>
+
+1.  Hover over the message, select the **More actions** <img src={useBaseUrl('/img/ui/dots-horizontal_F01D8.svg')} alt="Use the More icon to access additional message options." className="theme-icon" /> icon, and then select **Quarantine for Review**.
+2.  Select a **reason** for quarantining the message, and add a comment explaining why you're quarantining it, when required.
+3.  Select **Submit**.
+
+You’ll see a confirmation that your message was quarantined. Mattermost may hide the quarantined message based on how your system admin has configured Data Spillage Handling workflows. You can’t quarantine the same message twice.
+
+## If your message is quarantined
+
+A message being quarantined isn’t a disciplinary action. Quarantined messages help to protect sensitive data across your organization.
+
+If another user quarantines one of your messages, you’ll receive a direct message from the **Data Spillage Bot** explaining which message was quarantined and why. If Mattermost has hidden your message, the direct message won’t contain the quarantined message content.
+
+You'll receive another direct message once reviewers take action.
+
+- If your message is removed, review the reason why it was quarantined, and adjust how you share information in the future.
+- If your message is kept, no further action is required of you.
+
+Contact your reviewer or system admin if you need clarification about actions taken or next steps.

+## Use Markdown
+
+You can also format your messages in Mattermost using Markdown to control [text styling](#text-style), [links](#links), [headings](#headings), [lists](#lists), [code blocks](#code-blocks), [in-line code](#in-line-code), [in-line images](#in-line-images), [horizontal lines](#horizontal-lines), [block quotes](#block-quotes), [tables](#tables), and [math formulas](#math-formulas). Markdown makes it easy to format messages: type a message as you normally would, then use formatting syntax to render the message a specific way. For a guide to using Markdown in Mattermost, [see this blog post](https://mattermost.com/blog/laymans-guide-to-markdown-on-mattermost/).
+
+![Formatting markdown controls the look and feel of text messages.](/images/messagesTable1.png)
+
+### Text style
+
+You can use either `_` or `*` around a word or phrase to make it italic, or `__` or `**` around a word or phrase to make it bold.
+
+<Tip>
+
+Common formatting keyboard shortcuts are supported. Bold text by pressing <kbd>Ctrl</kbd> <kbd>B</kbd> on Windows and Linux, or <kbd>⌘</kbd> <kbd>B</kbd> on Mac. Italicize text by pressing <kbd>Ctrl</kbd> <kbd>I</kbd> on Windows or Linux, or <kbd>⌘</kbd> <kbd>I</kbd> on Mac.
+
+</Tip>
+
+- `*italics*` (or `_italics_`) renders as *italics*
+- `**bold**` renders as **bold**
+- `***bold-italic***` renders as <img src={useBaseUrl('/images/bold_italics.png')} width="100" alt="Bold Italics" />
+- `~~strikethrough~~` renders as <img src={useBaseUrl('/images/strikethrough.png')} width="100" alt="Strike Through" />
+
+### Links
+
+<Tip>
+
+Format selected message text as a link by pressing <kbd>Ctrl</kbd> <kbd>K</kbd> on Windows and Linux, or by pressing <kbd>⌘</kbd> <kbd>K</kbd> on Mac.
+
+</Tip>
+
+#### Channel links
+
+Create a link to a public channel in a message by typing `~` followed by the channel name (e.g. `~roadmap`). Channel members see private channel names returned.
+
+#### Labeled links
+
+Create labeled links by putting the desired text in square brackets `[ ]` and the associated link in round brackets `( )`.
+
+`[Check out Mattermost!](https://.mattermost.com/)`
+
+Renders as: [Check out Mattermost!](https://mattermost.com/)
+
+### Headings
+
+Make a heading by typing `#` and a space before your title. For smaller headings, use more `#`'s.
+
+``` text
+## Large Heading
+### Smaller Heading
+#### Even Smaller Heading
+```
+
+Renders as:
+
+![Large Heading](/images/Headings1.png)
+
+Alternatively, you can underline the text using equal signs `===` or hyphens `---` to create headings.
+
+``` text
+Large Heading
+-------------
+```
+
+Renders as:
+
+![Smaller Heading](/images/Headings2.png)
+
+### Lists
+
+Create a list by using asterisks `*`, hyphens `-`, and/or plus signs `+` interchangeably as bullets. Indent bullet points by adding two spaces in front each one.
+
+``` text
+* item one
+- item two
+  + item two sub-point
+```
+
+Renders as:
+
+- item one
+- item two
+  - item two sub-point
+
+Make an ordered list by using numbers instead:
+
+``` text
+1. Item one
+1. Item two
+1. item three
+```
+
+Renders as:
+
+1.  Item one
+2.  Item two
+3.  Item three
+
+You can also start a list at any number:
+
+``` text
+4. The first list number is 4.
+1. The second list number is 5.
+1. The third list number is 6.
+```
+
+Renders as:
+
+4.  The first list number is 4.
+5.  The second list number is 5.
+6.  The third list number is 6.
+
+Make a task list by including square brackets `[ ]`. Mark a task as complete by adding an `x`.
+
+``` text
+- [ ] Item one
+- [ ] Item two
+- [x] Completed item
+```
+
+Renders as:
+
+![List](/images/checklist.png)
+
+### Code blocks
+
+Creating a fixed-width code block is recommended for pasting multi-line blocks of code or other text output because it's easier to read with fixed-width font alignment. Examples include block text snippets, ASCII tables, and log files. Rendered code blocks include a **Copy** option to copy the contents of the code block.
+
+This can be accomplished by placing three backticks (```` ``` ````) on the line directly above and directly below your code:
+
+````text
+```
+this is my
+code block
+```
+````
+
+<Tip>
+
+Type three backticks (```` ``` ````), press <kbd>Shift</kbd> <kbd>Enter</kbd> on Windows or Linux, or <kbd>⇧</kbd> <kbd>↵</kbd> on Mac, `<type_your_code>`, press <kbd>Shift</kbd> <kbd>Enter</kbd> on Windows or Linux, or <kbd>⇧</kbd> <kbd>↵</kbd> on Mac again, then type three more backticks (```` ``` ````).
+
+</Tip>
+
+Or by indenting each line by four spaces:
+
+```text
+    this is my
+    code block
+```
+
+### Syntax highlighting
+
+To add syntax highlighting, type the language to be highlighted after the ```` ``` ```` at the beginning of the code block. Mattermost also offers four different code themes (GitHub, Solarized Dark, Solarized Light, and Monokai) that can be changed in **Settings \> Display \> Theme \> Custom Theme \> Center Channel Styles**.

+
+### In-line images
+
+In-line images are images added within lines of text. You can control whether all in-line images over 100px in height are automatically collapsed or expanded in messages by setting a [user preference](/end-user-guide/preferences/manage-your-display-options), or by using the `/collapse` and `/expand` slash commands.
+
+To add in-line images to text, use an exclamation mark `!` followed by the `alt text` in square brackets `[ ]`, then the `image URL` in round brackets `( )`. You can add hover text after the link by placing the text in quotes `" "`.
+
+Example:
+
+``` text
+![alt text](URL of image "Hover text")
+```
+
+If the height of the original image is more than 500 pixels, Mattermost sets the image height at 500 pixels and adjusts the width to maintain the original aspect ratio.
+
+You can set the width and height of the displayed image after the URL of the image by using an equals sign `=` followed by values for both width and height `##x##`. If you set only the width, Mattermost adjusts the height to maintain the original aspect ratio.
+
+<Warning>
+
+The native apps do not support fixed width and height and will display the full-size image.
+
+</Warning>
+
+Examples:
+
+``` text

+## Region navigation
+
+Mattermost has eight regions that can be focused for navigation. Use <kbd>F6</kbd> in the desktop app, or use <kbd>Ctrl</kbd> <kbd>F6</kbd> in a browser repeatedly to move focus and loop through the regions in this order:
+
+1.  Message list region
+2.  Message input region
+3.  Right-hand side message list region
+4.  Right-hand side message input region
+5.  Team menu region
+6.  Channel sidebar region
+7.  Channel header region
+8.  Search
+
+![Navigate through the sections of Mattermost using a keyboard.](/images/navigation.gif)
+
+## Message navigation
+
+When the message list region is focused, use the <kbd>↑</kbd> or <kbd>↓</kbd> arrow keys to navigate through messages and reply threads. Press <kbd>Tab</kbd> to navigate through message actions.
+

+
+### Message composition
+
+Mattermost is compatible with most popular screen readers, such as [Apple VoiceOver](https://www.apple.com/ca/accessibility/vision/) or [JAWS for Windows](https://www.freedomscientific.com/products/software/jaws/). A custom readout is composed for each message by combining the message elements and reading them together in full sentences. Message elements will read in the following order:
+
+1.  Header: Author, timestamp, message type (i.e. parent post or reply)
+2.  Main Content: The message content typed by the author
+3.  Attachments: The number of attachments (if applicable)
+4.  Emoji Reactions: The number of unique emoji reactions (if applicable)
+5.  Saves/Pins: If a message is saved or pinned (if applicable)
+
+For example, a message read by a screen reader may sound like the following:
+
+``` text
+Eric Sethna at 12:57pm Thursday June 13th wrote a reply "Thanks for the review", 3 attachments, 2 reactions, message is saved and pinned.
+```
+
+## Channel sidebar navigation
+
+When the channel sidebar region is focused, use the <kbd>↑</kbd> or <kbd>↓</kbd> arrow keys to focus individual sidebar sections, such as Insights, Threads, Favorites, custom categories, public channels, private channels, and direct messages. Press <kbd>Tab</kbd> to navigate through channels or other buttons within a sidebar section.

+title: "Learn about Mattermost roles"
+---
+<PlanAvailability slug="all-commercial" />
+
+There are 6 types of user roles with different permission levels in Mattermost: [system admin](#system-admin), [team admin](#team-admin), [channel admin](#channel-admin), [member](#member), [guest](#guest), and [deactivated](#deactivated).
+
+<Tip>
+
+To view a list of users on the team and what their roles are, you need to be A team admin using Mattermost in a web browser or the desktop app. Open the Team menu and select **Manage Members**.
+
+</Tip>
+
+## System admin
+
+The first user added to a newly-installed Mattermost system is assigned the system admin role. System admins are allowed to perform any actions on the system, and only a system admin can make changes to another system admin user account in Mattermost.
+
+The system admin is typically a member of the IT staff and has all the privileges of a team admin, along with the following additional privileges:
+
+- Access to the System Console in any team site.
+- Ability to change any setting on the Mattermost server available in the System Console.
+- Ability to promote and demote other users from Member role to system admin role (and vice versa).
+- Ability to promote and demote other users to and from Guest role.
+- Ability to deactivate user accounts and to reactivate them.
+- Access to private channels, but only if given the link to the private channel.
+
+A system admin can view and manage users in **System Console \> User Management \> Users**. They can search users by name, filter users by teams, and filter to view other system admins, guests, as well as activated and deactivated users.
+
+### Grant personal access tokens
+
+System admin also can enable [personal access tokens](https://developers.mattermost.com/integrate/admin-guide/admin-personal-access-token/) for user accounts. This gives specific users permissions to create personal access tokens via **System Console \> Users**.
+
+In addition, a system admin can optionally set the following permissions for the account, which are useful for integrations and bot accounts:
+
+- **post:all**: Allows the account to post to all Mattermost channels including direct messages.
+- **post:channels**: Allows the account to post to all Mattermost public channels.
+
+## Team admin
+
+When a team is first created, the person who set it up is made a team admin. It is a team-specific role, meaning that someone can be a team admin for one team but only a member on another team. Team admins have the following privileges:
+
+- Access to the **Team Settings** menu.
+- Ability to change the team name and import data from Slack export files.
+- Access to the **Manage Members** menu, where they can control whether team members are a **Member** or a **Team Admin**.
+- Ability to manage all aspects of a team, such as joining and managing private channels they're not a member of.
+- Ability to create and manage [attribute-based channel membership policies](/administration-guide/manage/admin/abac-team-channel-policies) for channels within the team, from the **Channel Membership** tab in Team Settings, when ABAC is enabled by a System Admin (Enterprise Advanced).
+- From Mattermost v11.10, ability to define [attribute-based team membership rules](/administration-guide/manage/admin/abac-team-membership) that control who can be a member of the team itself, from the **Team Membership** tab in Team Settings, when ABAC is enabled by a System Admin (Enterprise Advanced).
+
+## Channel admin
+
+The person who creates a channel is assigned the channel admin role for that channel. People with the channel admin role have the following privileges:
+
+- Ability to assign the channel admin role to other members of the channel.
+- Ability to remove the channel admin role from other holders of the channel admin role.
+- Ability to remove members from the channel.
+- Ability to configure channel actions that automate tasks based on trigger conditions, such as [joining a channel](/end-user-guide/collaborate/join-leave-channels#join-a-channel) or [sending a message](/end-user-guide/collaborate/send-messages) in a channel.
+
+Depending on your system configuration, channel admins can be granted special permissions by the system admin to rename and delete channels.

+This is the default role given to users when they join a team. Members have basic permissions on a Mattermost team. See the [advanced permissions backend infrastructure](/administration-guide/onboard/advanced-permissions-backend-infrastructure) documentation for details.
+
+## Guest
+
+A guest is a role with restricted permissions. Guests enable organizations to collaborate with users outside of their organization, and control what channels they are in and who they can collaborate with. See the [guest accounts](/administration-guide/onboard/guest-accounts) documentation for details on working with guest accounts.
+
+## Deactivated
+
+A system admin can deactivate user accounts via **System Console \> Users**. A list of all users on the server can be searched and filtered to make finding users easier. Select the user's role and in the menu that opens, then select **Deactivate**. See the [deactivate user accounts admin](/administration-guide/configure/user-management-configuration-settings#deactivate-users) documentation for details.
+
+When **Deactivate** is selected, the user is logged out of the system, and receives an error message if they try to log back in. The user no longer appears in channel member lists, and they are removed from the team members list. A deactivated account can also be reactivated from the System Console, in which case the user rejoins channels and teams that they previously belonged to.
+
+Direct message channels with deactivated users are hidden in users' sidebars, but can be reopened using the **More...** button or by pressing <kbd>Ctrl</kbd> <kbd>K</kbd> on Windows or Linux, or <kbd>⌘</kbd> <kbd>K</kbd> on Mac.
+
+Mattermost is designed as a system-of-record, so there isn't an option to delete users from the Mattermost system, as such an operation could compromise the integrity of message archives.
+
+<Note>
+
+AD/LDAP user accounts can't be deactivated from Mattermost; they must be deactivated from your Active Directory.

+
+<Note>
+
+- All Mattermost customers can start, join, and participate in 1:1 audio calls with optional screen sharing.
+- For group calls up to 50 concurrent users, Mattermost Enterprise, Professional, or Mattermost Cloud is required.
+- Enterprise customers can also [record calls](#record-a-call), enable [live text captions](/end-user-guide/collaborate/make-calls#live-captions-during-calls) during calls, and [transcribe recorded calls](#transcribe-recorded-calls). We recommend that Enterprise self-hosted customers looking for group calls beyond 50 concurrent users consider using the [dedicated RTCD service](/deployment-guide/calls/calls-deployment-guide).
+- Mattermost Cloud users can start calling right out of the box. For Mattermost self-hosted deployments, System admins need to enable and configure the plugin [using the System Console](/administration-guide/configure/plugins-configuration-settings#calls).
+
+</Note>
+
+<PlanAvailability slug="academy-calls" />
+
+## Join a call
+
+To join a call, select **Join call** in a channel, group message, or direct message. Any active team member in a channel or message can join a call, whether it's a public or private channel, or a group or direct message.
+
+<Tip>
+
+- You can share a call's link to use in a meeting request or share with other people. The link is unique to each channel, and contains the channel's ID, so it doesn't change between calls. Use the `/call link` slash command to generate a shareable link. The call link is valid for long as the channel is active. When a channel is archived or deleted, the share link becomes invalid.
+- If someone from outside of the organization wants to join a call, you need to provide them with a guest account, and add them to the channel. Users who are archived or not registered can't join a call.
+
+</Tip>
+
+From Mattermost v9.4:
+
+- You can join the same call using a web browser, the desktop app, and the mobile app. You can mute, unmute, react, share your screen, and configure voice settings independently for each Mattermost client you're using. You'll appear multiple times as a call participant in the call widget when you join one call on multiple clients.
+- You'll see incoming call notifications for direct and group messages when a new call is started. Multiple calls will result in multiple incoming call notifications. If you're already in a call, and you receive a new incoming call notification, Mattermost prompts you to **Join** the incoming call, or dismiss the notification.
+
+## Start a call
+
+<Tabs>
+<TabItem value="web-desktop" label="Web/Desktop">
+
+To start a call, select **Start call** in the channel header. When you start a call, you become the call host by default. See the [host controls](#host-controls) section below for details on host controls available to ensure calls run smoothly.
+
+<Tip>
+
+- When you start a call in a channel, you're muted by default. In a direct or group message you're unmuted by default.
+- You can move the call widget to a different area of your screen.
+- Alternatively, you can start a call using the `/call start` slash command.
+
+</Tip>
+
+</TabItem>
+<TabItem value="mobile" label="Mobile">

+
+![Tap on Start Call to start a call in the channel.](/images/mobile-start-a-call-in-a-channel.gif)
+
+After starting the call, audio will come through the device's speaker or a Bluetooth device, if connected. On Android, audio output will automatically switch to a Bluetooth device if one is connected during a call. You can tap the **Speaker** icon to manually select the output device.
+
+On iOS, audio will automatically come through a connected device. You can override this behavior by tapping the **Speaker** button. Audio will then come through the speaker. However, you cannot manually select an output device on iOS at this time.
+
+</TabItem>
+</Tabs>
+
+
+## Host controls
+
+From Mattermost v9.9, and Mattermost mobile v2.17, call host controls are available and include the ability to [transfer host duties](#transfer-host-duties), [remove call participants](#remove-call-participants), [stop a screen share](#stop-a-screen-share), [mute or unmute participants](#mute-participants), [lower raised hands](#lower-raised-hands), and [end the call for everyone](#end-the-call-for-everyone).
+
+Host controls are available to call hosts and admins in both the call widget by selecting the **More** <img src={useBaseUrl('/img/ui/dots-horizontal_F01D8.svg')} alt="Use the More icon to access additional message options." className="theme-icon" /> icon next to a participant's name, and in the expanded the call window as hosts hover over a call participant in the list.
+
+### Transfer host duties
+
+Transfer host duties to another call participant by accessing the host controls and selecting **Make host**. Once host duties are transferred to someone else, you can't access host controls unless they're transferred back to you. System admins can change the host at any time.
+
+### Remove call participants
+
+Remove a call participant from an active call by accessing the host controls and selecting **Remove from call**, then confirm by selecting **Yes, remove**. The call participant is notified that they've been removed from the call by the host.
+
+### Stop a screen share
+
+Stop a call participant's screen share by accessing the host controls and selecting **Stop screen share**.
+
+### Mute participants
+
+Invite muted participants to unmute their microphone by accessing the host controls and selecting **Ask to unmute**. The call particpant is prompted to decide whether unmute or stay muted.
+
+You can mute the microphone of specific particpants by accessing the host controls and toggling the particpant's mute icon. Mute all call particpants by selecting **Mute all**.
+
+### Lower raised hands
+
+Lower a raised hand by accessing the host controls and selecting **Lower hand**. The participant is notified that their hand was lowered by the host.
+
+### End the call for everyone
+
+From Mattermost v10.2 and mobile v2.19, call hosts who choose to leave a call are prompted to confirm whether they want to leave or end the call for all participants.
+
+## Share your screen
+
+During a call, call participants can share their screen with other call participants, unless your system admin has [disabled your ability to do so](/administration-guide/configure/plugins-configuration-settings#allow-screen-sharing).
+
+<Note>
+
+Screensharing is available in the Mattermost desktop app or a web browser. The ability to screenshare using the mobile app isn't supported.
+
+</Note>
+
+To share your screen:
+
+1.  In the call widget, select **Start presenting**.
+2.  Select the screen you want to share.
+3.  To stop sharing, select the **Stop presenting** icon or the **Stop sharing** option.
+
+### Share audio during screen sharing
+
+From Mattermost Calls plugin v1.9.0, you can share audio along with your screen during screen sharing. To enable this feature, you must first turn on the **Share sound with screen** preference in your Calls settings by going to **Settings \> Plugin Preferences \> Calls**. This setting is stored locally on each client and is not synchronized across devices.
+
+<Note>
+
+Audio sharing support varies by platform and browser:
+
+**Web browsers:**
+
+- **Chrome-based browsers only** (Google Chrome, Chromium, Microsoft Edge): When sharing a browser tab, you'll have the option to include audio from that tab. On Windows only, you can also share system sounds when sharing the entire screen.
+- **Other browsers**: Audio sharing is not supported.
+
+**Desktop app:**
+
+- **Windows and Linux**: System audio is shared when sharing the entire screen.
+- **macOS**: Audio sharing is not supported due to system limitations.
+
+</Note>
+

+
+## Record a call
+
+<PlanAvailability slug="ent-plus" />
+
+From Mattermost v7.7, if you're the host of a meeting, you can record the call, unless your system admin has [disabled the host's ability to do so](/administration-guide/configure/plugins-configuration-settings#enable-call-recordings).
+
+Call recordings include audio, any screen sharing during the call, and text transcriptions, when [enabled](/administration-guide/configure/plugins-configuration-settings#enable-call-transcriptions).
+
+The default setting for a recording is 60 minutes, but your system admin may [change the recording duration](/administration-guide/configure/plugins-configuration-settings#maximum-call-recording-duration) as needed. You'll receive a reminder 10 minutes before the recording limit is reached. If your call is going to continue beyond the recording limit, allow the first recording to complete, then start a new recording immediately after.
+
+When you stop recording, the recording file is posted in the call thread as an MP4 file attachment. It's available to all users in the channel both during the call, and after the call has ended.
+
+To record a call:
+
+<Tabs>
+<TabItem value="web-desktop" label="Web/Desktop">
+
+1.  Select **Start call** in the header of the channel, group message, or direct message.
+2.  Select the pop-out icon.
+3.  In the call widget, select the **Record** button.
+4.  To stop recording, select the **Record** button again.
+
+</TabItem>
+<TabItem value="mobile" label="Mobile">
+
+To start recording, use the `/call recording start` slash command. When you're finished recording, use the `/call recording stop` slash command.
+
+![Use '/call recording start' to start recording a call](/images/mobile-start-a-call-recording-using-slash-commands.gif)
+
+![Use '/call recording stop' to stop recording the call.](/images/mobile-stop-a-call-recording-using-slash-commands.gif)
+
+Alternatively, expand the call window using the arrows in the top-right of the active call banner. Then select the **Record** button. To finish, tap on **Stop Recording** button.
+
+![Tap on Record to start recording a call.](/images/mobile-start-a-call-recording-using-call-banner.gif)

+</Tabs>
+
+
+## Live captions during calls
+
+<PlanAvailability slug="ent-plus" />
+
+From Mattermost v9.7, and Mattermost mobile app v.2.16, all call participants can display real-time text captions by selecting the **More** <img src={useBaseUrl('/img/ui/dots-horizontal_F01D8.svg')} alt="Use the More icon to access additional message options." className="theme-icon" /> icon and **Show live captions** when the call is being recorded, and when [live captions are enabled](/administration-guide/configure/plugins-configuration-settings#enable-live-captions). Live captions can be helpful in cases where noise is preventing you from hearing the audio of participants clearly.
+
+By default, live captions display in English. Your Mattermost system admin can [specify a different language for live captions](/administration-guide/configure/plugins-configuration-settings#live-captions-language) in the System Console.
+
+<Note>
+
+- The ability to enable live captions during Mattermost calls is currently in [Beta](/administration-guide/manage/feature-labels#beta).
+- Your system admin must enable [call recordings](/administration-guide/configure/plugins-configuration-settings#enable-call-recordings) to enable live captions.
+
+</Note>
+
+## Transcribe recorded calls
+
+<PlanAvailability slug="ent-plus" />
+
+From Mattermost v9.4, and Mattermost mobile app v.2.13, call recordings can include text captions, and a transcription text file can be generated, unless your system admin has [disabled the ability to transcribe call recordings](/administration-guide/configure/plugins-configuration-settings#enable-call-transcriptions).
+
+When call recording stops, the transcription file is posted in the call thread as a TXT file attachment. It's available to all users in the channel both during the call, and after the call has ended. Additionally, users viewing the call recording can show or hide text captions using the Closed Captioning option in the video player.
+
+<Note>
+
+- The ability to enable recorded call transcriptions is currently in [Beta](/administration-guide/manage/feature-labels#beta).
+- Your system admin must enable [call recordings](/administration-guide/configure/plugins-configuration-settings#enable-call-recordings) to enable recorded call transcriptions.
+
+</Note>
+
+## Frequently asked questions
+
+### Can I set a ring tone for incoming calls?
+
+Yes! From Mattermost v8.0 and Calls v0.17.0, desktop app and web users can go to **Settings \> Notifications \> Desktop Notifications** to enable Mattermost to alert you to incoming calls through direct or group messages with a specific ring tone and a desktop notification, unless the system admin has [disabled your ability to do so](/administration-guide/configure/plugins-configuration-settings#enable-call-ringing).
+
+### Is video supported?
+
+From Mattermost Calls plugin v1.12.0, experimental video support is available in direct message (DM) calls on the desktop and web apps. It's disabled by default; a system admin can enable it using the [Enable video calls in DMs (Experimental)](/administration-guide/configure/plugins-configuration-settings#enable-video-calls-in-dms-experimental) plugin setting in the System Console. The following limitations apply:
+
+- Video is available in DM calls only. All other calls continue to support voice calling and screen sharing only.
+- Video isn't available on the mobile app. Mobile users can't start a video call, and when they join a DM call that includes video, it behaves like an audio call — they hear voice and see shared screens, but don't see video.
+- Call recordings don't capture video. Recordings include voice and screen sharing only.
+
+### Can I password-protect a call?
+
+No. Any member with sufficient permission to access the channel can join the call.
+
+### Is there encryption?
+
+Media (audio/video) is encrypted using security standards as part of WebRTC. It's mainly a combination of DTLS and SRTP. It's not e2e encrypted in the sense that in the current design all media needs to go through Mattermost which acts as a media router and has complete access to it. Media is then encrypted back to the clients so it's secured during transit. In short: only the participant clients and the Mattermost server have access to unencrypted call data.
+
+### Are there any third-party services involved?
+
+The only external service used is Mattermost official STUN server (`stun.global.calls.mattermost.com`) which is configured as default. This is primarily used to find the public address of the Mattermost server. The only information sent to this service is the IP addresses of clients connecting as no other traffic goes through it. It can be removed in the System Console if you want to provide an `ICE Host Override` setting instead.
+
+## Troubleshooting
+
+### My audio doesn't work when I join a call
+
+If you can hear the other participants in the call but they can't hear you, select the Gear icon <img src={useBaseUrl('/img/ui/settings-outline_F08BB.svg')} alt="Use the Settings icon to customize your Mattermost user experience." className="theme-icon" /> next to the call end button in the widget. From there, you can check and change your audio output and microphone settings. Select <img src={useBaseUrl('/img/ui/settings-outline_F08BB.svg')} alt="Use the Settings icon to customize your Mattermost user experience." className="theme-icon" /> again to close the menu. Alternatively, you can [manage your audio and microphone preferences](/end-user-guide/preferences/manage-your-plugin-preferences) in **Settings**.
+
+### My call is disconnected after a few seconds
+
+This is usually a sign that the underlying UDP channel has not been established and the connection times out after ~10 seconds. When the connection has been established correctly an `rtc connected` line should appear in the client-side logs (JS console). There isn't a single solution as it depends on your infrastructure/deployment specifics. However, if you're a system or network admin, you may need to open up the UDP port or configure the network accordingly.
+
+### I can't screen share using Mattermost desktop on macOS
+
+There's a known bug on macOS with some versions of Chrome (which is used by Mattermost desktop). If you've given screen sharing permissions to Mattermost desktop, and are still unable to screen share, do the following:
+
+1.  Quit Mattermost.
+2.  Open Terminal.
+3.  In the terminal, run: `tccutil reset ScreenCapture Mattermost.Desktop`
+4.  Restart Mattermost and start a call.
+5.  Select **Screen share** and give it permissions again.
+6.  Restart Mattermost again.
+
+If the issue persists please post on the Mattermost Community Server in the [Developer: Calls](https://community.mattermost.com/core/channels/developers-channel-call) channel to troubleshoot further.
+
+## Debugging
+
+If you experience issues with calls, collecting information is helpful as you can share it with us for debugging purposes.
+
+As with any other issue, but more importantly with calls, it’s very useful to let us know the date and time that the problem occurred, with as much detail as possible so that information can be cross-checked with server logs. Also please include any reproduction steps if applicable. Other important information includes:
+
+- Browser/app version
+- Operating system type and version
+
+### JS console logs
+

+In the top menu bar of the app, select **View \> Developer Tools \> Developer Tools for Current Tab**. In the logs that are generated, right-click and select **Save as** to download the logs.
+
+#### Mobile app
+
+You can access and share debug logs from **Account screen \> Settings \> Report a problem**.
+
+### Call stats dump
+
+In cases where there are audio/video issues, difficulty in hearing other participants, and/or stuttering video and/or choppy audio, run the `/call stats` slash command in the channel where the call is currently active. This returns a JSON object via an ephemeral message. Additionally, run the `/call logs` command to review the client logs for the last call session.
+
+You can run this command in an active call or after leaving the call in question. However, we will only save data for the last joined call so joining again will delete the previous call's feedback.
+
+### WebRTC internals (Chrome and Firefox only)
+
+This is an additional method for Chrome and Firefox users in cases where there are audio/video issues, difficulty in hearing other participants, and/or stuttering video and/or choppy audio.
+
+#### Chrome browser (recommended)
+
+Open `chrome://webrtc-internals/` in the browser that you're using for the active call.
+
+#### Firefox browser
+
+Open `about://webrtc` in the browser that you're using for the active call.
+
+### Share information
+
+Debug information is helpful to our community as there may be other community members having the same issue as you. We recommend that debug information be shared in either of the two options below:
+
+- Post in [Developers: Calls](https://community.mattermost.com/core/channels/developers-channel-call) channel: prefer this method when possible but keep in mind the channel is public.
+- Post in [Team: Calls](https://community.mattermost.com/private-core/channels/calls-team) channel: use this channel if posting sensitive information.

+From Mattermost v10.1, you can bookmark up to 50 links or files to the top of channels for quick and easy access, unless your system admin has disabled your ability to do so. Bookmarks display directly under channel headers. Files added as channel bookmarks are also [searchable](/end-user-guide/collaborate/search-for-messages) in Mattermost.

+## Open a bookmark
+
+Opening a channel bookmark works the same way as selecting a file link or attachment in a message. Select or tap a bookmark to view the file or link.
+
+From Mattermost v10.11, bookmarks containing `mattermost://` links open directly in the desktop app using deep linking. This turns bookmarks into one-click shortcuts to channels, threads, or messages, letting you jump straight to key assets in Mattermost quickly and easily.

+## Add members to a channel
+
+Any member of a channel can add other members to public or private channels, unless your system admin has restricted access to do so.
+
+When a channel has [attribute-based access controls](/administration-guide/manage/admin/attribute-based-access-control) enabled, you'll see details about which user attributes are permitted access to the channel. Behavior differs by channel type:
+
+- **Private channels**: Only users who meet the requirements appear in search results when adding members, and only those users can be added.
+- **Public channels**: All eligible team members appear in search results, and users who meet the recommended attributes are labeled **Recommended**. Anyone can still be added because public-channel access controls are advisory and never remove existing members.
+
+<Tabs>
+<TabItem value="web-desktop" label="Web/Desktop">
+
+To add members to a channel:
+
+1.  Select the channel name at the top of the center pane to access the drop-down menu, then select **Add Members**.

+title: "Mention people in messages"
+---
+<PlanAvailability slug="all-commercial" />
+
+When you want to get the attention of specific Mattermost users, you can use @mentions. Mattermost supports the following types of @mentions:
+
+- [@username](#username)
+- [@channel](#channel-and-all)
+- [@all](#channel-and-all)
+- [@here](#here)
+- [@groupname](#groupname)
+- [@customusergroupname](#customusergroupname)
+
+<Note>
+
+- If you forget to mention someone in a message, editing the existing message to add an @mention won't trigger new @mention notifications, desktop notifications, or notification sounds.
+- Mattermost supports mentions for names that include accents (also known as diacritics). Names like Zoë, Jesús, Sørina, François, André, Jokūbas, Siân, KŠthe, or Fañch are returned in autocomplete results.
+
+</Note>
+
+## @username
+
+You can mention a teammate by using the *@* symbol plus their username to send them a mention notification.
+
+Type *@* or the full-width "＠" (U+FF20) to bring up a list of team members who can be mentioned. To filter the list, type the first few letters of any username, first name, last name, or nickname.
+
+<Note>
+
+Mattermost v11.3 added support for full-width @, improving the experience for Japanese IME and other international keyboard users. Existing @ mentions are unaffected. See the :doc:v11.3 release notes \</product-overview/mattermost-v11-changelog\> for details.
+
+</Note>
+
+<Tip>
+
+Using Mattermost in a web browser or the desktop app, you can also press the <kbd>↑</kbd> and <kbd>↓</kbd> arrow keys to scroll through entries in the list, and press <kbd>ENTER</kbd> on Windows or Linux, or <kbd>↵</kbd> on Mac, to select the person to mention. When selected, the username replaces the full name or nickname.
+
+</Tip>
+
+The following example sends a special mention notification to Alice, whose username is **alice**. The notification alerts her of the channel and message where she was mentioned. If Alice is away from Mattermost and has email notifications turned on, she'll receive an email alert of her mention along with the message text.
+
+``` text
+@alice how did your interview go with the new candidate?
+```
+
+If the person you mentioned doesn't belong to the channel or the team, a system message is posted to let you know, and you're given the option to add the person to the channel. You are the only one who can see this message.
+
+## @channel and @all
+
+You can mention an entire channel by typing `@channel` or `@all`. All members of the channel receive a mention notification that behaves the same way as if the members had been mentioned personally. If used in Town Square, it notifies all members of your team.
+
+You can ignore channel-wide mentions in specific channels in the **Channel Menu \> Notification Preferences \> Ignore mentions for @channel, @here and @all**.
+
+``` text
+@channel great work on interviews this week. I think we found some excellent potential candidates!
+```
+
+If a channel has five or more members, you may be prompted to confirm that you want notifications sent to everyone in the channel.
+
+## @here
+
+You can mention everyone who is online in a channel by typing `@here`. This sends a desktop notification and push notification to members of the channel who are online. It's counted as a mention in the sidebar. Members who are offline don't receive a notification. When they return to Mattermost they won't see a mention counted in the channel sidebar. Members who are away receive a desktop notification only if they have notifications set to **For all activity**, and they won't see a mention counted in the sidebar.
+
+``` text
+@here can someone complete a quick review of this?
+```
+
+If a channel has five or more members, you may be prompted to confirm that you want notifications sent to everyone in the channel.
+
+You can ignore channel-wide mentions in specific channels by enabling the **Channel Menu \> Notification Preferences \> Ignore mentions for @channel, @here, and @all** option.
+
+## @groupname
+
+<PlanAvailability slug="ent-plus" />
+
+This feature enables system admins to configure custom mentions for [LDAP synced groups](/administration-guide/onboard/ad-ldap-groups-synchronization) via the Group Configuration page. This functionality is also supported on the mobile app (from v1.34) if the AD/LDAP groups feature is enabled. The mobile app supports auto-suggesting groups, highlights group member mentions, and also provides a warning dialog when a mention will notify more than five users.
+
+Once enabled for a specific group, users can mention and notify the entire group in a channel (similar to `@channel` or `@all`). Members of the group in that channel will receive a notification. If members of the group mentioned aren't members of the channel, the user who posted the mention is prompted to invite them.
+
+Group mention identifiers (slugs) use the LDAP group name by default. To customize/rename the slug:
+
+1.  Open **System Console \> User Management \> Groups**.
+2.  Select **Edit** next to the group you want to edit.
+3.  In **Group Profile \> Group Mention** enter the new slug.
+4.  Select **Save**.
+
+As with `@username` mentions, use *@* to bring up a list of groups that can be mentioned. To filter the list, type the first few letters of any group. Press the <kbd>↑</kbd> and <kbd>↓</kbd> arrow keys to scroll through entries in the list, and then press <kbd>Enter</kbd> on Windows or Linux, or pressing <kbd>↵</kbd> on Mac to select the group you want to mention.
+
+``` text
+@dev-managers great work hitting all of our code coverage goals this quarter!
+```
+
+## @customusergroupname
+
+You can add groups of users to a channel or team by [creating a custom group](/end-user-guide/collaborate/organize-using-custom-user-groups) and @mentioning that custom group in a channel.
+
+- Mattermost prompts to you to add any users who aren't already members of that channel to the channel.
+- From Mattermost v9.1, you're given the option to add any users who aren't already members of that team to the team, if you have the permissions to do so.
+
+## Words that trigger mentions
+
+You can customize words that trigger mention notifications in **Settings \> Notifications \> Words That Trigger Mentions**. By default, you receive mention notifications for your username and for `@channel`, `@all` and `@here`. You can choose to have your first name be a word that triggers mentions.
+
+You can add a list of customized words to get mention notifications for by typing them into the input box, separated by commas. This is useful if you want to be notified of all posts on certain topics, such as "interviewing" or "marketing".
+
+## See all recent mentions
+
+Select **@** to the right of the **Search** box to query for your most recent @mentions and words that trigger mentions (excluding LDAP group mentions).
+
+![See your most recent @mentions](/images/recent-mentions.png)
+
+Your recent mentions are shown for all of your teams.
+
+Select **Jump** next to a search result in the right-hand sidebar to jump the center pane to the channel and location of the message with the mention.
+
+## Confirmation dialog warnings
+
+When your system admin has configured Mattermost to require confirmations for @mentions, you must confirm any mention that will trigger notifications for more than five users before sending the notification.
+
+This confirmation dialog only appears when your system admin has configured this setting in the System Console. See our [configuration settings](/administration-guide/configure/site-configuration-settings#show-channel-all-or-here-confirmation-dialog) product documentation for details. This configuration setting is supported on the Mattermost Mobile App (from v1.34) if the [AD/LDAP groups](/administration-guide/onboard/ad-ldap-groups-synchronization) feature is enabled.
+
+## Mention highlights
+
+Valid mentions will have highlighted font text with some exceptions, for example if mentions are disabled at the channel level. The highlighted text becomes a hyperlink when a username is displayed. When the username is selected, the profile popover is displayed.
+
+When mentions trigger a notification, the user being notified will see highlighted font text and highlighted font background. This functions as an identifier of which mentions in the post triggered a notification for the user.

See the [configuration](/administration-guide/configure/site-configuration-settings#persistent-notifications) documentation for details.
+
+</Note>
+
+## Receive persistent notifications
+
+You must have desktop and/or mobile push notifications enabled to receive persistent notifications. How you're notified depends on your [notifications preferences](/end-user-guide/preferences/manage-your-notifications) for desktop and mobile push notifications. You won't be notified when your availability is set to **Do Not Disturb**, or if you're [Out of Office](/end-user-guide/preferences/set-your-status-availability#set-your-availability). Learn more about managing and customizing how you receive [Mattermost notifications](/end-user-guide/preferences/manage-your-notifications).
+
+Urgent messages show a red mention badge which remains visibible until you view the message. Selecting the **Acknowledge** icon (when present) won't impact the urgent red mention badge.
+
+![Example of the channel sidebar with both regular and urgent unread messages.](/images/urgent-message.png)
+
+To stop receiving persistent notifications, you can reply to the thread, select the **Acknowlege** icon (when present), or react to the thread with an emoji. Persistent notifications also stop if the original message is deleted, or if the maximum number of persistent notifications are sent.
+
+## Request acknowledgements
+
+You can additionally request that recipients actively acknowledge the message to track that messages have been seen and actioned. By default, marking a message as Urgent priority automatically requests an acknowledgement.
+
+When you request acknowledgement of a message, an **Acknowledge** <img src={useBaseUrl('/img/ui/Ack-Button-Default.svg')} alt="Select the Acknowledge button to indicate that you've read it and taken necessary action." /> button is added below the sent message.

+## Known issues
+
+Threaded discussions were released as generally available in Mattermost v7.0, including significant server performance improvements and more flexible configuration options for system admins to enable the feature by default. We highly recommended [upgrading Mattermost](/administration-guide/upgrade/upgrading-mattermost-server) to take advantage of configuration and performance enhancements.

+
+Custom groups reduce noise and improve focus by notifying the right people in a channel at the right time, while maintaining transparency for all members in that channel. Custom user groups let you notify up to 256 users at a time rather than notifying users individually.
+
+For example, perhaps you want to @mention a cross-functional team about a bug fixes needed for an upcoming feature release, without notifying everyone else in the channel. Using a custom group notifies the cross-functional team immediately, while keeping important stakeholders in the loop on the status of the feature release.
+
+Or perhaps you want to add a group of users to a team and a channel. When you @mention a custom group in a channel, Mattermost prompts you to add anyone from that custom group who isn't already a channel and team member. See the [invite people to your workspace](/end-user-guide/collaborate/invite-people) documentation for details.
+
+Once a custom user group has been created, you can mention that group the same way you @mention another Mattermost member. See the [mention people in messages](/end-user-guide/collaborate/mention-people) documentation for details.
+
+<Note>
+
+- System admins need to enable this feature. See our [Mattermost Configuration Settings](/administration-guide/configure/site-configuration-settings#enable-custom-user-groups) documentation for details.
+- From Mattermost v7.2, system admins can limit who can manage custom user groups through the Custom Group Manager system admin role. See the [delegated granular administration](/administration-guide/onboard/delegated-granular-administration) documentation for details.
+- The ability to create custom user groups on mobile will be available in a future release. @mentions for custom user groups on mobile work the same as [LDAP-synced groups](/end-user-guide/collaborate/mention-people#groupname).
+
+</Note>
+
+## Create a custom group
+
+1.  Using Mattermost in a web browser or the desktop app, select <img src={useBaseUrl('/img/ui/plus_F0415.svg')} alt="The Plus icon provides access to channel and direct message functionality." className="theme-icon" /> at the top of the channel sidebar, then select **Create New User Group**.
+2.  Specify a name and mention. The mention is the handle you use to @mention a notification to the group. Group names must be unique across the Mattermost [workspace](/end-user-guide/end-user-guide-index). If a name is in use as a channel name, display name, or another custom group's name, it won't be available.
+3.  Search for and select members to add to the custom user group, then select **Create Group**.
+
+## Review group members
+
+From Mattermost v7.8, using Mattermost in a web browser or the desktop app, select a group mention in a thread to display a list of group members.
+
+## Manage custom user groups
+
+You can review and filter the list of custom groups, add people to an existing group, edit the group name or mention, leave the group, or archive the group.
+
+To manage a custom user group in a web browser or the desktop app, select **User Groups** from the Products menu, then select the group you want to modify.
+
+![Access tools to manage user groups.](/images/access-user-groups.png)

+
+A team is a digital [workspace](/end-user-guide/end-user-guide-index) where you and your teammates can collaborate in Mattermost. Depending on how Mattermost is [set up](/administration-guide/configure/experimental-configuration-settings#primary-team) in your organization, you can belong to one team or multiple teams, and [access to the team](/end-user-guide/collaborate/team-settings#access-settings) can be open or restricted.
+
+Users with the **Create Teams** permission can [create new teams](#create-a-team) and [manage team settings](/end-user-guide/collaborate/team-settings) for existing teams. System admins can grant the **Create Team** permission to roles via the [System scheme](/administration-guide/onboard/advanced-permissions#system-scheme) or the [Team override scheme](/administration-guide/onboard/advanced-permissions#team-override-scheme).
+
+## Single team versus multiple teams
+
+Mattermost can be deployed both to a single team and to multiple teams. Currently, we recommend deploying to a single team for the following reasons:
+
+- Single team deployments promote communication across the organization. When you add multiple teams, groups can become isolated.
+- Integrations (e.g., webhooks and slash commands) are only persistent across single team deployments.
+
+However, some Mattermost customers prefer multiple team deployments for the following reasons:
+
+- Teams are useful when there is a purpose for each of them. For example, one team is used for staff members and another team for external users.
+- Performance is better when users are scattered across multiple teams instead of all in the same one. With multiple teams, there is less content to load per team or channel switch and database queries are faster.
+- Creating a shared team for all users, and using advanced permissions to control who can create channels and add members to the shared team, improves cross-team collaboration when using multiple teams. Additionally, an annoucement banner can be used to provide system-wide announcements.
+- The platform supports multiple team functionalities including general search, saved posts, and recent mentions across teams.
+
+## Team sidebar
+
+If you belong to more than one team, a team sidebar displays to the left of the channel sidebar. Drag teams to reorder them in the sidebar. You can also use keyboard shortcuts to navigate between teams.
+
+![Navigating between teams in Mattermost.](/images/teams.gif)
+
+## Create a team
+
+You can create a team using a web browser or the desktop app by selecting a team name, and then selecting **Create a Team**, unless your system admin has disabled your ability to do so.
+
+![Create a new team by selecting the team name.](/images/create-team.gif)
+
+### Team name and URL selection
+
+There are a few details and restrictions to consider when selecting a team name and team URL.
+
+<Note>
+
+If your system admin has enabled anonymous team and channel URLs (available in Mattermost Enterprise Advanced from v11.6.0), team creation becomes a single-step flow and you will not be prompted to choose a team URL. The URL is assigned automatically.
+
+</Note>
+
+#### Team name
+
+This is the display name of your team that appears in menus and headings.
+
+- Team names can contain any letters, numbers, or symbols.
+- Team names are case sensitive.
+- Team names must be 2 - 64 characters in length.
+
+#### Team URL
+
+If your system admin has not enabled anonymous URLs, you choose a team URL during team creation. The team URL is part of the web address that navigates to your team on the system domain, `https://domain.com/teamurl/`.
+
+- Teams may contain only lowercase letters, numbers, and dashes.
+- Teams must start with a letter and cannot end in a dash.
+- Teams must be 2 - 64 characters in length.
+- Team names cannot start with the following restricted words: `admin`, `api`, `channel`, `claim`, `error`, `files`, `help`, `landing`, `login`, `mfa`, `oauth`, `plug`, `plugins`, `post`, `signup`, or `playbooks`.
+
+## Join a team
+
+You can join any open teams, or join any team you receive an invitation to join.
+
+If you haven't yet joined any teams in Mattermost, you're prompted to join available teams when you [log in to Mattermost](/end-user-guide/access/access-your-workspace).
+
+You can be a member of multiple teams at the same time. To join additional teams, select the current team name, choose **Join Another Team**, and select the name of the team you want to join.
+
+![Select a team name to join another team.](/images/join-team.png)
+
+<Note>
+
+When your organization uses [team membership access policies](/administration-guide/manage/admin/abac-team-membership), the list of teams you can join depends on your user attributes. Public teams whose requirements you meet are marked **Recommended**, and private teams whose requirements you don't meet aren't listed at all.
+
+</Note>
+
+From Mattermost Mobile v2.40.0, you can join another team from the mobile app by tapping the team name in the channel list header, then tapping **Join Another Team**.
+
+## Leave a team
+
+Users can also choose to remove themselves from a team, from **Team menu \> Leave Team**. This will remove the user from the team, and from all public channels and private channels on the team.
+
+From Mattermost Mobile v2.40.0, you can leave a team from the mobile app when you belong to more than one team. In the channel list, tap the team name, tap **Leave team**, then confirm.
+
+They will only be able to rejoin the team if it's open, or if they receive a new invitation. If they do rejoin, they will no longer be a part of their old channels.
+
+## Remove people from teams
+
+Team admins can remove users from a team via **Team menu \> Manage Members \> Remove From Team** in the dropdown menu beside a user entry.
+
+When a user is removed from a team, the team will no longer be visible or accessible in their team sidebar. If they currently have the team open, they are redirected to the first team that appears in their team sidebar. If they didn't belong to any other teams, the user is sent to the team selection page.
+
+Removing a user from the team does not deactivate the account. The user will still be able to log in to the site, and join other teams. They will also be able to rejoin the team they were removed from if they receive another invite. When a private team has a team membership access policy, invited users must also satisfy that policy. Users can also rejoin if the team is set to [Public Team](/end-user-guide/collaborate/team-settings#discoverability) and they meet any other join restrictions, such as approved email domains. Team membership access policies on public teams are advisory and don't prevent users from rejoining. If the user does rejoin the team, they will no longer belong to the channels they were previously a part of, and they will lose all Admin privileges if they had them previously.
+
+A system admin can also remove users from teams via **System Console \> Users**, and selecting the dropdown beside a user entry and selecting **Manage Teams**. The list of teams an individual user belongs to can be viewed on the user's profile page via **System Console \> Users** and selecting the member's name from the list provided in the **User Configuration** screen.
+
+## Archive a team
+
+A Mattermost system admin can archive teams they no longer need by going to **System Console \> Teams**, selecting a team, and selecting **Archive Team**. Archived teams can be unarchived if needed.
+
+When a team is archived, the team will no longer be visible or accessible in the team sidebar for any user. If users currently have the team open when it's being archived, users are redirected to the first time that appears in their team sidebar. If users didn't belong to any other teams, users are sent to the team selection page.
+
+<Note>
+
+Archiving a team doesn't remove the team data from the Mattermost database. Teams may still be accessible by using the Mattermost API.

+
+<Tip>
+
+It's easy to return to a message in progress with global message drafts. Find all of your draft messages in the **Drafts** view available at the top of the channel sidebar. See the [draft messages](/end-user-guide/collaborate/send-messages#draft-messages) documentation for details.
+
+</Tip>
+
+## Organize discussions into threads
+
+When you reply to messages, those replies are [organized into a discussion thread](/end-user-guide/collaborate/organize-conversations). Threaded discussions are easy to follow and allow multiple parallel conversations to occur at the same time without confusion.
+
+Using Mattermost in a web browser or the desktop app, replies appear indented slightly in the center pane to indicate that they are child messages of a parent message. Selecting the reply link opens a sidebar in the right-hand sidebar in a web browser and the desktop app. To expand the right-hand sidebar to its full width, select the **Expand** icon with two arrows at the top of the sidebar.
+
+![Expand right-hand sidebar to its full width](/images/expand-sidebar.png)

+There are times when you want to send a message, but you don’t want it sent immediately. For example, it may be after working hours for the recipient. Scheduled messages can include a [priority](/end-user-guide/collaborate/message-priority), [request acknowledgements](/end-user-guide/collaborate/message-priority#request-acknowledgements), include [file attachments](/end-user-guide/collaborate/share-files-in-messages), and include anything that a non-scheduled message can contain, except [slash commands](/integrations-guide/run-slash-commands).

+- **Edit scheduled post**: Make changes to the draft inline before its sent.
+- **Copy text**: Copy the draft text.
+- **Reschedule message**: Change when the message should be sent.

+
+## Troubleshoot scheduled messages
+
+Scheduled messages may fail for the following reasons:
+
+- You're no longer a member of the channel.
+- The channel is archived.
+- The channel is read-only.
+- The Mattermost server was down for more than 24 hours. Mattermost processes scheduled posts up to 24 hours old, so in cases where the server is down for short time, scheduled messages will be processed. Scheduled messages older than 24 hours may fail to send.
+
+If a scheduled message fails to send, you'll be alerted 2 ways:
+
+- A red badge displays a total scheduled post count in the left pane next to **Drafts**. <img src={useBaseUrl('/img/ui/schedule-count-red-badge.png')} alt="Total count of scheduled messages." />
+- An alert banner displays on the **Scheduled** tab

+You can't reschedule a failed message, but you can schedule a new replacement message.

+</Tabs>
+
+
+## Search modifiers
+
+You can apply search modifiers to any search to reduce the number of results returned. Select a search modifier to add it to the Search field. Supported modifiers are described below. Your search results include messages from all of your teams.
+
+### `from:` and `in:`
+
+- Use `from:` to find messages or files from specific users.
+  - For example, searching `from:john.smith` only returns content from your direct message history with John Smith.
+  - From Mattermost v10.10, you can use `from:` in cross-team searches to find messages from specific users across all teams you're a member of.
+- Use `in:` to find messages or files posted in specific public channels, private channels, direct messages, or group messages. You can specify channels by display name or channel ID.
+  - For example, searching `Mattermost in:town-square` only returns results in the Town Square public channel that contains the term `Mattermost`, while searching `Mattermost in:john.doe` only returns results that contains the term `Mattermost` in your direct message history with John Smith.
+
+### `before:`, `after:`, and `on:`
+
+- Use `before:` to find messages or files posted before a specified date.
+
+  - For example, searching `website before: 2018-09-01` returns messages or files containing the term `website` posted prior to September 1, 2018.
+
+- Use `after:` to find messages or files posted after a specified date.
+
+  - For example, searching `website after: 2018-08-01` returns messages or files containing the term `website` posted after August 1, 2018.
+
+- Use both `before:` and `after:` together to search in a specified date range.
+
+  - For example, searching `website before: 2018-09-01 after: 2018-08-01` returns all messages or files containing the term `website` posted between August 1, 2018 and September 1, 2018.
+
+- Use `on:` to find messages or files posted on a specific date. Use the date picker to select a date, or type it in YYYY-MM-DD format.
+
+  - For example, searching `website on: 2018-09-01` returns messages or files containing the term `website` posted on September 1, 2018.
+
+  ![Select the on modifier to specify messages or files for a specific a date.](/images/calendar2.png)
+
+### Exclusions
+
+Use the hyphen `-` symbol to exclude terms from your search results. For example, searching `test -release` only returns results that include the term `test` and exclude the term `release`.
+
+This exclusion modifier can be used in combination with other modifiers to further refine search results. For example, searching `test -release -in:release-discussion -from:eric` returns all results with the term `test`, excludes posts with the term `release`, excludes posts made in the `release-discussion` channel, and excludes messages sent in direct messages by `eric`.
+
+### Quotation marks
+
+Use quotation marks `" "` to return search results for exact terms. For example, searching `"Mattermost website"` returns messages containing the exact phrase `Mattermost website`, but doesn't return results containing `Mattermost` and `website` as separate terms.
+
+### Wildcards
+
+Use the asterisk `*` symbol at the end of the word to perform a wildcard search. The wildcard search returns all words that begin with the specified letters. The wildcard in search cannot be used at the beginning or in the middle of a word. For example, searching `rea*` returns messages or files containing words like `reach`, `reason`, `reality`, `real`, and other words starting with `rea`. However, searches like `*each` and `re*ch` are invalid wildcard searches.
+
+### Hashtags
+
+Hashtags are searchable labels for messages. Anyone can create a hashtag in a message by using the pound sign `#` followed by alphanumeric or other unicode characters. Hashtag examples include: `#bug`, `#marketing`, `#user_testing`, `#per.iod`, `#check-in`, `#마케팅`.
+
+Valid hashtags:
+
+- Don't start with a number.
+- Are at least three characters long, excluding the `#`.
+- Are made up of alphanumeric or other unicode characters.
+- May contain dots, dashes, or underscores.
+
+To search for messages containing hashtags, select a hashtag in an existing post, or type the hashtag (including the pound `#` symbol) into the search bar.
+
+<Note>
+
+Hashtags don't link to channels. If you have a channel named “Marketing”, selecting a `#marketing` hashtag does not take you to the Marketing channel. To link to public channels, use the tilde `~` symbol followed by the channel name. For example `~marketing`.
+
+</Note>
+
+## Search public channels you haven't joined
+
+<PlanAvailability slug="ent-plus" />
+
+From Mattermost v11.6, when your system admin [enables searching public channels without membership](/administration-guide/configure/environment-configuration-settings#allow-searching-public-channels-without-membership), search results can include messages from public channels you haven't joined. Results are scoped to teams you belong to, so you'll only see messages from public channels in your teams. This setting doesn't affect private channels — you can only search private channels you're a member of.
+
+## Notes about performing Mattermost searches
+
+- Multiple-word searches return results that contain *all* of your search criteria.
+- Search modifiers can help narrow down searches. See the [search modifiers](#search-modifiers) section for details.
+- You can search Archived channels as long as you're a member of that channel.
+  - If you're unable to see messages or files in archived channels in your search results, ask your system admin if **Allow users to view archived channels** has been disabled via **System Console \> Site Configuration \> Users and Teams**.
+  - To remove archived channels from your search results, you can leave the Archived channels.
+- Like many search engines, common words such as `the`, `which`, and `are` (known as "stop words"), as well as two-letter and one-letter search terms, are not shown in search results because they typically return too many results. See the [Technical notes about searching](#technical-notes-about-searching) section below for details.
+- IP addresses (e.g. `10.100.200.101`) don't return results.
+
+## Technical notes about searching
+
+By default, Mattermost uses full text search support included in PostgreSQL. Select the **product menu** <img src={useBaseUrl('/img/ui/products_E82F.svg')} alt="Navigate between Channels, collaborative playbooks, and boards using the product menu icon." className="theme-icon" /> then select **About Mattermost** to see which database you’re using.
+
+- Stop words are filtered out of search results. See [PostgreSQL](https://www.postgresql.org/docs/10/textsearch-dictionaries.html#TEXTSEARCH-STOPWORDS) database documentation for a full list of applicable stop words.
+- URLs don’t return results.
+- Hashtags or recent mentions of usernames containing a dash don't return results.
+- Terms containing a dash return incorrect results since dashes are ignored in the search engine.
+- From Mattermost v7.1, search results respect the `default_text_search_config` value instead of being hardcoded to English. We recommend that Mattermost system admins review this value to ensure it's set correctly.

+## Rewrite messages with AI
+
+You can use AI to enhance your messages before sending them. This feature helps you improve writing quality, fix spelling, adjust message length, or transform your text based on specific needs.
+
+From Mattermost v11.5, when you use AI Rewrite while composing a reply in a thread, the AI incorporates context from the thread to generate suggestions that better fit the ongoing conversation.
+
+From Mattermost v11.7, Rewrite is accessed through the **AI Actions** <img src={useBaseUrl('/img/ui/creation-outline_F1C2B.svg')} alt="AI Actions icon." className="theme-icon" /> menu, alongside any custom prompts your system admin has made available.
+
+On Web/Desktop or Mobile:
+
+> 1.  Type your message in the message compose field.
+> 2.  Open the **AI Actions** <img src={useBaseUrl('/img/ui/creation-outline_F1C2B.svg')} alt="AI Actions icon." className="theme-icon" /> menu from the message actions, then select **Rewrite**.
+> 3.  Select a bot from the list of available AI agents.
+> 4.  Choose from available rewrite options:
+>     - **Improve writing**: Enhance clarity and professionalism
+>     - **Fix spelling**: Correct spelling and grammar errors
+>     - **Shorten**: Make your message more concise
+>     - **Elaborate**: Add more detail and context
+>     - **Simplify**: Use clearer, easier-to-understand language
+>     - **Summarize**: Condense your message to key points
+>     - **Custom prompt**: Specify your own transformation instructions
+> 5.  Review the AI-generated suggestion. Select **Regenerate** to try again or **Discard** to return to your original message.
+> 6.  Select **Send** <img src={useBaseUrl('/img/ui/send_F048A.svg')} alt="Select the Send icon to post your message." className="theme-icon" />
+
+<Tip>
+
+From Mattermost v11.7, system admins can publish custom prompts that appear alongside Rewrite in the **AI Actions** <img src={useBaseUrl('/img/ui/creation-outline_F1C2B.svg')} alt="AI Actions icon." className="theme-icon" /> menu. If you don't see a custom prompt you expect, check with your system admin.
+
+</Tip>
+
+<Note>
+
+Messages that have been rewritten using AI are automatically marked as AI-generated content for transparency. Your system admin must [configure AI agents](/administration-guide/configure/agents-admin-guide) for the rewrite feature to be available.

+
+## Send burn-on-read messages
+

+
+From Mattermost v7.7, when composing new messages, it's easy to return to a message in progress later, unless your system admin has [disabled global drafts](/administration-guide/configure/site-configuration-settings#enable-server-syncing-of-message-drafts) in the System Console.
+
+By default, message drafts are synchronized on the Mattermost server and are accessible everywhere you access Mattermost, including a web browser or the desktop app. Limit drafts to your current Mattermost client only by going to **Settings \> Advanced \> Allow message drafts to sync with the server** to disable draft synchronization.

+## Deep links
+
+Deep links are a powerful feature in Mattermost that allow you to create direct links to specific teams, channels, messages, or threads. These links can be used to quickly navigate to important content within Mattermost, enhancing collaboration and efficiency.
+
+Deep links can also be used, in combination with bots, scripts, and integrations, to trigger specific actions within Mattermost.
+
+From Mattermost v10.11, [channel bookmarks](/end-user-guide/collaborate/manage-channel-bookmarks) containing `mattermost://` open directly in the desktop app using deep linking. This turns channel bookmarks into one-click shortcuts that enable you jump straight to key assets in Mattermost quickly and easily.
+
+### Format deep links
+
+Deep links must be formatted in Mattermost as follows:
+
+- Deep link to a team: `mattermost://<your-Mattermost-server-URL>/<team-name>`
+- Deep link to a channel: `mattermost://<your-Mattermost-server-URL>/<team-name>/channels/<channel-name>`
+- Deep link to a channel message or thread: `mattermost://<your-Mattermost-server-URL>/<team-name>/pl/<post-id>`

+
+![Access team settings from the team name.](/images/team-settings.png)
+
+## Info settings
+
+Info settings provide configuration options for how teams are displayed to users.
+
+### Team name
+
+Your **Team Name** is displayed on the login screen, and in the top of the channel sidebar for your team.
+
+Team names can contain any letters, numbers, or symbols, must be 2 - 64 characters in length, and are case-sensitive.
+
+<Note>
+
+Team names don't support [some unicode characters](https://www.w3.org/TR/unicode-xml/#Charlist).
+
+</Note>
+
+### Team description
+
+Your **Team Description** is displayed when viewing the list of teams available to join and in the tooltip when hovering over the team name in the team sidebar.
+
+You can enter a description up to 50 characters in length.
+
+<Note>
+
+Team descriptions don't support [some unicode characters](https://www.w3.org/TR/unicode-xml/#Charlist).

+
+### Team icon
+
+A **Team Icon** displays in the team sidebar. By default, the team icon contains the first two letters of the team name.
+
+To customize the team icon:
+
+1.  Select **Team Settings**.
+2.  Select the Team Icon **Edit** option.
+
+![Manage the team icon from Team Settings.](/images/edit-team-icon.png)
+
+3.  Select an icon image in BMP, JPG, or PNG format. We recommend using square images with a solid background color since transparency in PNG icons fills with a white background in the team sidebar.
+4.  Select **Save**.
+
+<Tip>
+
+When a team icon is configured, select **Remove image** to reset the team icon to the default icon containing the first two letters of the team name.
+
+</Tip>
+
+## Access settings
+
+Access settings enable the ability to control who can join the team.
+
+### Discoverability
+
+System and team administrators control whether the team is public or private using two selection cards:
+
+- **Public Team** — anyone on the server can find the team, and join it if they meet any other join restrictions, such as approved email domains. The team appears on the server landing page and in the **Teams you can join** page.
+- **Private Team** — only invited members can join. The team isn't listed for users who aren't already members.
+
+<Note>
+
+From Mattermost v11.10, these cards replace the **Allow any user to join** checkbox. This change applies to every team on every deployment. **Public Team** is equivalent to the checkbox being enabled, and **Private Team** is equivalent to it being disabled.
+
+</Note>
+
+<Important>
+
+Switching a team from **Public Team** to **Private Team** regenerates the team's invite code. This creates a new invitation link and invalidates any link shared previously.
+
+</Important>
+
+<Tip>
+
+When a team is set to **Public Team**, users looking for more teams to join will also see this team in the list when they select the <img src={useBaseUrl('/img/ui/plus_F0415.svg')} alt="The Plus icon provides access to channel and direct message functionality." className="theme-icon" /> icon in the team sidebar.
+
+</Tip>
+
+On teams managed by AD/LDAP group synchronization, the cards aren't shown. Instead, the Access tab displays a message noting that members of the team are added and removed by linked groups.
+
+### Users with a specific email domain
+
+System and team administrators can limit who can join the team based on their email domain. Enable this option to specify approved email domains. Separate multiple email domains using spaces, commas, pressing <kbd>Tab</kbd>, or pressing <kbd>Enter</kbd>.
+
+When enabled, only users that have an email domain from the approved domain list is able to join the team. The setting's intent is solely to gate joining a team. Once joined, team members will be able to update their email to a non-approved domain without any restrictions. Additionally, team members who joined prior to approved domains being specified won't be removed from the team once approved email domains are configured and enforced.
+
+<Important>
+
+Mattermost deployments using [email authentication](/administration-guide/configure/authentication-configuration-settings#enable-sign-in-with-email) must also enable the [require email verification configuration setting](/administration-guide/configure/authentication-configuration-settings#require-email-verification) for domain restrictions to be effective.

+## Team Membership
+
+<PlanAvailability slug="entry-adv" />
+
+From Mattermost v11.10, the **Team Membership** tab is available to Team Admins when [Attribute-Based Access Control (ABAC)](/administration-guide/manage/admin/attribute-based-access-control) is enabled by a System Admin. It allows Team Admins to view the system policy applied to their team and define attribute-based rules that control who can be a member of the team itself.
+
+On private teams these rules are enforced: users who don't match can't join, and members who no longer match are removed at the next sync. On public teams the rules are advisory — qualifying users are highlighted as recommended, but anyone can still join.
+
+See [Team membership access policies](/administration-guide/manage/admin/abac-team-membership) for full details.
+
+## Channel Membership
+
+<PlanAvailability slug="entry-adv" />
+
+The **Channel Membership** tab is available to Team Admins when [Attribute-Based Access Control (ABAC)](/administration-guide/manage/admin/attribute-based-access-control) is enabled by a System Admin. It allows Team Admins to create and manage attribute-based membership policies for private and public channels within the team. On private channels the policies are enforced. On public channels they're advisory — matching users can be added automatically or shown the channel as recommended, but no one is removed.
+
+<Note>
+
+This tab was previously labelled **Membership Policies**. It was renamed in Mattermost v11.10 to distinguish it from the new **Team Membership** tab.
