Change how often you receive missed activity emails
Missed activity emails make it easy to catch up on what you’ve missed when you’ve been away from Teams. You can choose how often you’d like to receive missed activity emails in Outlook. By default, you’ll receive a missed activity email once every hour.
Select Settings and more > Settings > Notifications.
Go to the Email section. Beside Missed activity emails, you can choose how often you’d like to receive a missed activity email.
