Check a channel for notifications in Teams
You know you have unread messages and unseen activity in a channel because its name appears bold. If you favorite the channel, it stays visible in your list.
You also receive notifications when someone @mentions you or replies to a conversation you're in, so that's another way you know a channel is active.
Check your activity feed
If you're worried about knowing whether a conversation needs your attention, rest assured—all your notifications appear in your Activity feed, so you'll never miss a thing. You get a notification whenever someone:
@mentions you (you also see your @mentions in the conversation)
@mentions teams and channels you belong to
Replies to conversations you're part of
Replies to your replies
Use the command box
Another way to check your notifications is to use the command box at the top of Teams.
Type /unread to see your unread channel notifications
Type /mentions to see all your @mentions

Show, hide, or pin a team or channel in Teams
Only channels you favorite are visible from your team list. A bold channel is an active channel that has unread messages.
If a channel shows a number, that's how many times you’ve been @mentioned. For @teams mentions, you'll see this team icon in your activity feed.
You'll also receive notifications in your activity feed when someone @mentions you or replies to a conversation you're in.
