You need to ensure that all unused teams expire and are deleted automatically. The solution must meet the following requirements. The teams must expire 365 days from their creation date…

Question

Explanation

This question tests your ability to configure the Microsoft 365 Groups Expiration Policy, which automatically expires and deletes unused Microsoft Teams (backed by Microsoft 365 Groups) after a defined period and routes orphaned-team notifications to a specified administrator.

Approach. Sign in to the Microsoft 365 portal, then navigate to Microsoft Entra ID (Azure Active Directory) > Groups > Expiration. Set the 'Group lifetime (in days)' to 365, set 'Email contact for groups with no owners' to adminABCDE123456.onmicrosoft.com, and set the policy to apply to 'All' Microsoft 365 groups (which underpin Teams). Once saved, any team whose owner does not renew it will receive expiration notifications at 30, 15, and 1 day before expiry; if unrenewed the team is soft-deleted and permanently purged after 30 days. This single policy satisfies both requirements-the 365-day lifetime and the orphaned-team notification address.

Concept tested. Microsoft 365 Groups / Microsoft Teams Expiration Policy configuration in Microsoft Entra ID (Azure AD) - including setting group lifetime in days and specifying a fallback notification email for ownerless (orphaned) groups to prevent stale Teams from accumulating in the tenant.
