Configure expiration for Office 365 groups (preview)
You can now manage the lifecycle of Office 365 groups by setting expiration features for them. You can set expiration for only Office 365 groups in Azure Active Directory (Azure AD). Once you set a group to expire:
- Owners of the group are notified to renew the group as the expiration nears
- Any group that is not renewed is deleted
- Any Office 365 group that is deleted can be restored within 30 days by the group owners or the administrator
Setting expiration for Office 365 groups requires an Azure AD Premium license or an Azure AD Basic EDU license for all members of the groups to which expiration settings are applied.
For Azure AD Basic EDU licensed customers: to configure this policy for the first time, use the Azure Active Directory PowerShell cmdlets. After that, you can update the expiration settings using either PowerShell or the Azure AD portal, with an account that's a User Account Administrator or Global Administrator in your Azure AD tenant.
For information on how to download and install the Azure AD PowerShell cmdlets, see Azure Active Directory PowerShell for Graph - Public Preview Release 188.8.131.52.
Set group 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.
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 you first set up expiration, any groups that are older than the expiration interval 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.
