@Mentions

Users can tag their colleagues in a comment on messages using the @mentions feature in the activity tab. This gives users the option to add a comment while tagging the message for their colleague's attention. If users have their notifications enabled, they will receive a notification when they have been tagged using @mentions on a message and will be able to view the message in the Following in All Teams tab. If they do not have their notifications enabled, the message will simply show up in the Following in All Teams tab. For more information on how to set up notifications, see the Notifications article here. 

Note: @mentions will only work if the user mentioned has access to the message through their teams. When you begin typing '@', you will only see members of the team you're currently in. 

To use @mentions:

1. Click on the message you wish to tag.
2. Expand the panel on the right side of the message.
3. Click into the Activity Tab.
4. Begin typing your comment in the comment box. When you are ready to tag a colleague, type @name. For example, if you chose to tag John Doe in the message, type @johndoe. Hit enter when you are done and the message will show your comment, and the action of tagging your colleague.
