📖 What is Microsoft 365 Groups Expiration Policy?
Microsoft 365 Groups Expiration Policy is a setting that automatically deletes inactive groups after a specified period unless the owner renews them. This prevents 'group sprawl' and ensures that the environment remains clean and manageable.
"Note that the group owner receives notifications before the group expires, giving them a chance to extend the life of the group."

🎯 How does Microsoft 365 Groups Expiration Policy appear on the MS-102 Exam?
You may be asked to recommend a solution for a company struggling with thousands of abandoned Teams and SharePoint sites. You must identify the expiration policy as the primary tool to automate cleanup.
A scenario might describe a situation where a critical department group was deleted because the owner left the company. You will need to explain how to use group exemptions to prevent this.
Expect questions about the notification process, where you must identify that only the group owners, not all members, receive the renewal prompts before the group is automatically deleted.
❓ Frequently Asked Questions
Can specific groups be excluded from the expiration policy?
Yes. Administrators can use the Set-UnifiedGroup PowerShell cmdlet to set the Expire parameter to False for specific groups, ensuring that critical organizational resources are never deleted automatically.
What happens to the group data once the expiration period ends?
The group enters a soft-deleted state for 30 days. During this window, an administrator can restore the group and all its associated content, including SharePoint sites and Mailboxes.
Does this policy affect traditional security groups or distribution lists?
No, this policy applies exclusively to Microsoft 365 Groups. Traditional security groups and distribution lists do not have built-in expiration policies and must be managed manually or via custom scripts.
