Microsoft Group Expiration Policy

Hi @Sunil KG

If the group was created via Planner, SharePoint, or any other app, the expiration notifications will always come via email. If the group was created via Teams, the group owner will receive an email and a notification to renew through the activity section. It's not recommended that you enable expiration on a group if your group owner doesn't have a valid email address.

30 days before the group expires, the group owners (or the email addresses that you specified for groups that don't have an owner) will receive an email allowing them to easily renew the group. If they don't renew it, they'll receive another renewal email 15 days before expiration. If they still haven't renewed it, they'll receive one more email notification the day before expiration.

This is behavior by design, you cannot configure the number of Group expiration notification emails.
