"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you want to do it for a specific OU, you can set the searchbase parameter.

$baseou = "OU=Users OU,dc=domain,dc=com"
Get-ADUser -Filter * -SearchBase $baseou| Set-ADUser -OfficePhone $null -PassThru
