My Office365 group was deleted inadvertently. Is there any way to restore it? There are important data and documents in it! Thanks in advance!
You could use Get-AzureADMSDeletedGroup
to display all deleted Office 365 groups in your tenant that are still available to restore.
Also, you could use Get-AzureADMSDeletedGroup –Id <objectId>
to verify the specific deleted group has not yet been permanently purged.
Once you have verified that the group is still available to restore, you could use Restore-AzureADMSDeletedDirectoryObject –Id <objectId>
to restore the group and its contents.
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.
Please refer to the official document: Restore a deleted Office 365 group in Azure Active Directory
