Hello SharePointers,

Below are the powershell script to look out for empty user groups using Powershell in SharePoint 2010,2013,2016,2019.

if (!(Get-PSSnapin Microsoft.Sharepoint.Powershell -ErrorAction SilentlyContinue))
{ Add-PSSnapin microsoft.sharepoint.powershell }

$site = “Your sharepoint site name”

$UsergroupCount = get-spsite $site | % {
$_.allwebs | % {
$web = $_
$web.groups | % {
[pscustomobject][ordered]@{
“GroupName” = $_.name
“WebName” = $web.Name
“UserCount” = $web.users.count
“Permissions” = ($web.roles | select -ExpandProperty name) -join “,”
}
}
}
}

$UsergroupCount

Happy SharePointing folks !!
