Channels typically contain many conversations — and many messages within those conversations — so it can be easy to overlook a message. To make sure a specific person on your team sees a particular message, tag them as you write your message by typing @username. (Replace “username” with the person’s user name, of course.) Or: After you type @, a menu opens listing the names of people in your organization. Click a name on this list to tag them in your message.) Once you post the message, the person will get a notification as a prompt to read it and respond to it.
You can also use this @ function to send a direct message (a one-on-one message) to a team member. Inside the search box at the top of the Microsoft Teams desktop app, type @ and their name (or type @ and click their name from the list that opens). Type a short message in the search box and press Enter or click the right arrow at the right end of the search box.
