When using the Microsoft Teams Mobile App, you can enable phone calls and messages to be silenced in a scheduled manner. If you don't want to receive phone calls after hours (or on weekends, for example,) this can stop those notifications from coming through. First, open your Microsoft Teams Mobile App. Click on your face icon:
Then, select "Notifications."
On the Notifications screen, you'll see options under "Block Notifications." One of those options is to block notifications "During Quiet Time."
From this screen, you can select "Quiet Hours," as well as "Quiet Days." This will ensure you won't get Teams notifications during the allotted time.
Using Quiet Time ensures you won't be notified when you don't want/need to be.
*Keep in mind, this feature is only available on the mobile version of Microsoft Teams.
