Remove disabled users from Distribution Lists & Security Groups in Active Directory

One of my clients had several disabled users showing up in distribution lists and security groups and this was creating unnecessary noise in email, alerts, etc. I highly encourage all administrators to keep their AD neat and tidy.

The following PowerShell script searches for disabled users in Groups and Distribution Groups and removes them:

# This script removes all disabled users from all security and distribution groups in the specified "searchOU"

Import-Module ActiveDirectory

$searchOU = "OU=Groups,DC=domain,DC=local"

$adgroup = Get-ADGroup -Filter 'GroupCategory -eq "Security" -or GroupCategory -eq "Distribution"' -SearchBase $searchOU
$adgroup | ForEach-Object{ $group = $_
	Get-ADGroupMember -Identity $group -Recursive | %{Get-ADUser -Identity $_.distinguishedName -Properties Enabled | ?{$_.Enabled -eq $false}} | ForEach-Object{ $user = $_
		$uname = $user.Name
		$gname = $group.Name
		Write-Host "Removing $uname from $gname" -Foreground Yellow
		Remove-ADGroupMember -Identity $group -Member $user -Confirm:$false
	}
}

# This script removes all disabled users from all security and distribution groups in the specified "searchOU"

Import-Module ActiveDirectory

$searchOU = "OU=Groups,DC=domain,DC=local"

$adgroup = Get-ADGroup -Filter 'GroupCategory -eq "Security" -or GroupCategory -eq "Distribution"' -SearchBase $searchOU

$adgroup | ForEach-Object{ $group = $_

Get-ADGroupMember -Identity $group -Recursive | %{Get-ADUser -Identity $_.distinguishedName -Properties Enabled | ?{$_.Enabled -eq $false}} | ForEach-Object{ $user = $_

$uname = $user.Name

$gname = $group.Name

Write-Host "Removing $uname from $gname" -Foreground Yellow

Remove-ADGroupMember -Identity $group -Member $user -Confirm:$false

}

Hope this helps!
