Managing Microsoft Teams notifications
You can adjust how you want to receive notifications from Teams. By default, both email and Teams are selected. If you don’t want to receive notification settings in Teams for a particular item, clear the checkbox.
Note
Notifications can only be managed by each user individually. Notifications can't be turned on or off globally for all users.
From the left menu, select Settings.
Select Notifications.
Scroll to the Microsoft Teams section to adjust your notification preferences.
