Restore a deleted Office 365 group in Azure Active Directory
When you delete an Office 365 group in the Azure Active Directory (Azure AD), the deleted group is retained but not visible for 30 days from the deletion date. This behavior is so that the group and its contents can be restored if needed. This functionality is restricted exclusively to Office 365 groups in Azure AD. It is not available for security groups and distribution groups. Please note that the 30-day group restoration period is not customizable.
Remove-MsolGroup because it purges the group permanently. Always use
Remove-AzureADMSGroup to delete an Office 365 group.
The permissions required to restore a group can be any of the following:
|Global administrator, Partner Tier2 support, and Intune administrator||Can restore any deleted Office 365 group|
|User administrator and Partner Tier1 support||Can restore any deleted Office 365 group except those groups assigned to the Company Administrator role|
|User||Can restore any deleted Office 365 group that they own|
View and manage the deleted Office 365 groups that are available to restore
Sign in to the Azure AD admin center with a User administrator account.
Select Groups, then select Deleted groups to view the deleted groups that are available to restore.
On the Deleted groups blade, you can:
- Restore the deleted group and its contents by selecting Restore group.
- Permanently remove the deleted group by selecting Delete permanently. To permanently remove a group, you must be an administrator.
View the deleted Office 365 groups that are available to restore using Powershell
The following cmdlets can be used to view the deleted groups to verify that the one or ones you're interested in have not yet been permanently purged. These cmdlets are part of the Azure AD PowerShell module. More information about this module can be found in the Azure Active Directory PowerShell Version 2 article.
Run the following cmdlet to display all deleted Office 365 groups in your tenant that are still available to restore.
Alternately, if you know the objectID of a specific group (and you can get it from the cmdlet in step 1), run the following cmdlet to verify that the specific deleted group has not yet been permanently purged.
Get-AzureADMSDeletedGroup –Id <objectId>
How to restore your deleted Office 365 group using Powershell
Once you have verified that the group is still available to restore, restore the deleted group with one of the following steps. If the group contains documents, SP sites, or other persistent objects, it might take up to 24 hours to fully restore a group and its contents.
Run the following cmdlet to restore the group and its contents.
Restore-AzureADMSDeletedDirectoryObject –Id <objectId>
Alternatively, the following cmdlet can be run to permanently remove the deleted group.
Remove-AzureADMSDeletedDirectoryObject –Id <objectId>
How do you know this worked?
To verify that you’ve successfully restored an Office 365 group, run the

- The plan for the group will appear in Planner
- Any SharePoint sites and all of their contents will be available
- The group can be accessed from any of the Exchange endpoints and other Office 365 workloads that support Office 365 groups
