  • Hi AdithyaDuyala,

    SharePoint groups are managed at site collection level.

    If you have the role inheritance broken at the sub-site, you can remove the association for specific groups. The result will be that group not having permissions for that site and not being displayed on the Site Permission page. However, the group will be available at the site collection level.

    Modify the PowerShell script as below:

    Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
    Function Delete-SPGroup($ssite)
        #Get the RootWeb
        $web = Get-SPWeb -Identity $ssite 
            # Check if web has Unique permission - Root webs always uses Unique permission 
                 if (($web.HasUniqueRoleAssignments) -and ($web.IsRootWeb -eq $false))
                        for($i=$web.RoleAssignments.Count-1;$i -ge 0; $i--)
                                    $group = $web.SiteGroups[$web.RoleAssignments[$i].Member.Name];
                                    Write-Host "Group Deleted-" $group -ForegroundColor Green 
        {   Write-host "Site doesn't have any unique permissions " $web.URL -ForegroundColor Red

    The PowerShell will delete the permission groups at sub site but won't affect the groups in root site collection.

  • We have tested the newly updated script and mentioned below are our findings.

    Although the subsites are getting deleted, the permission groups associated with the subsite are not being deleted. There is also one instance where the subsite was not deleted but the permission groups for that subsite was deleted.

    We had uploaded around 9 subsites for deletion and out of these 8 subsites were deleted, but the permission groups for these sub sites are intact. The permission group was deleted for the 9<sup>th</sup> subsite where the site has not been deleted. Please refer to the attachment labelled “Site Details” for additional information.

    Based on this, the script is not performing as it is expected to at the moment.
