Deleting deleted group connected SharePoint Online Sites

When a SharePoint Online site was deleted, it might have been connected to a M365 group. In this case it cannot be removed from deleted sites.

First delete the group from Entra (Azure AD)

Using PnP Powershell command Get-PnPDeletedMicrosoft365Group it is possible to find the deleted M365 Group, and remove it with Remove-PnPDeletedMicrosoft365Group:


PS /Users/martin> Get-PnPDeletedMicrosoft365Group

DisplayName                               Id                                   HasTeam SiteUrl
-----------                               --                                   ------- -------
PnP Microsoft 365 library test with group e351a3ff-1595-4979-b588-88038f993cc6 False

Remove-PnPDeletedMicrosoft365Group -Identity e351a3ff-1595-4979-b588-88038f993cc6

Afterwards the permanetly delete button works:

Bonus Feature: Since we are already connected, we can also use Get-PnPTenantDeletedSite and Remove-PnPTenantDeletedSite to remove the site permanently.
