System Admins can display a notice that’s visible to all users on the system via an announcement banner. The announcement banner is disabled by default, so System Admins must first enable this feature within the System Console or via the config.json file.

An example of an announcement banner displayed in Mattermost Channels notifying all users that the system will be going down for maintenance later that evening. System Admins enable the banner and customize the text to display, as well as configure whether or not users can dismiss the banner.

Note

The announcement banner is not displayed in the Boards or Playbooks tabs.

System Admins can display an announcement banner at the top of the user's screen.

By default, users can dismiss the banner until they log in again or until you update the banner. You can configure Mattermost to prevent users from dismissing the banner.

Update the banner by either changing the text of the banner or by re-enabling the banner after it’s been disabled. You can also control the text color and the background color.
