You can now manage the lifecycle of Office 365 groups by setting expiration for any Office 365 groups that you select. Once this expiration is set, owners of those groups are asked to renew their groups if they still need the groups. Any Office 365 group that is not renewed will be deleted. Any Office 365 group that was deleted can be restored within 30 days by the group owners or the administrator.
You can set expiration for only Office 365 groups.
Setting expiration for O365 groups requires that an Azure AD Premium license is assigned to
- The administrator who configures the expiration settings for the tenant
- All members of the groups selected for this setting
Set Office 365 groups expiration
Open the Azure AD admin center with an account that is a global administrator in your Azure AD tenant.
Open Azure AD, select Users and groups.
Select Group settings and then select Expiration to open the expiration settings.
On the Expiration blade, you can:
- Set the group lifetime in days. You could select one of the preset values, or a custom value (should be 31 days or more).
- Specify an email address where the renewal and expiration notifications should be sent when a group has no owner.
- Select which Office 365 groups expire. You can enable expiration for All Office 365 groups, you can select from among the Office 365 groups, or you select None to disable expiration for all groups.
- Save your settings when you're done by selecting Save.
For instructions on how to download and install the Microsoft PowerShell module to configure expiration for Office 365 groups via PowerShell, see Azure Active Directory V2 PowerShell Module - Public Preview Release 184.108.40.206.
Email notifications such as this one are sent to the Office 365 group owners 30 days, 15 days, and 1 day prior to expiration of the group.
The group owner can then select Renew group to renew the Office 365 group, or can select Go to group to see the members and other details about the group.
When a group expires, the group is deleted one day after the expiration date. An email notification such as this one is sent to the Office 365 group owners informing them about the expiration and subsequent deletion of their Office 365 group.
The group can be restored by selecting Restore group or by using PowerShell cmdlets, as described in Restore a deleted Office 365 group in Azure Active Directory.
If the group you're restoring contains documents, SharePoint sites, or other persistent objects, it might take up to 24 hours to fully restore the group and its contents.
- When deploying the expiration settings, there might be some groups that are older than the expiration window. These groups are not be immediately deleted, but are set to 30 days until expiration. The first renewal notification email is sent out within a day. For example, Group A was created 400 days ago, and the expiration interval is set to 180 days. When you apply expiration settings, Group A has 30 days before it is deleted, unless the owner renews it.
- When a dynamic group is deleted and restored, it is seen as a new group and re-populated according to the rule. This process might take up to 24 hours.
