Exchange Calendar

If you want to configure notifications from your Exchange Calendar, be it your personal calendar, shared calendar, or group calendar, go to your Outlook settings, click the gear icon on the ribbon, and click “View all Outlook settings” at the bottom.

Go to “General => Notifications” and find all the notification settings, like in-app and desktop pop-ups, for incoming emails and events.

In “Calendar => Events and invitations” settings, you can find default reminder settings that will pop up in Microsoft Teams.
