Notification tips and tricks
How to get all notifications for all activity
By default, you’ll only receive notifications for teams and channels that you haven’t hidden from your teams list.
Once you’ve got all your channels where you want them, you’ll start receiving notifications in Activity. If you’d also like to get these notifications on your desktop, select Settings > Notifications > and select Edit under Shown channels and select Banner and feed.
How to turn down the noise
Some ways to keep your focus on the activity that’s most important to you:
Turn off desktop notifications for activity you don’t need to respond to right away. Select either Feed only or Off.
Hide a channel to turn off activity and desktop notifications. Hidden channels will show in your list if a message is marked important or when someone @mentions you or the channel.
Set your presence to Do not disturb to get some quiet time. This won’t change your notification settings, but it will mute notifications until you change your presence back.
Quiet Hours for Mobile Notifications
If you don’t want notifications from Microsoft Teams on your mobile phone you can activate Quiet hours and/or Quiet days. During these hours or days you won’t get any notifications on your mobile phone, but you will still get calls.
