How to clear AD Users Mobile and Home phone number under the Telephone tab using PowerShell

[stamang]

Hello,

We have multiple users in AD who has a mobile number assigned under the Telephone tab; now, we want to clear the Mobile number for all user.

Is there a PowerShell script that I can use?

1. Get all users list from AD.

2. Remove listed users Mobile number

Your help would be much appreciated.

foreach ($user in $users) {
set-aduser $user -clear mobile
}

Why such difficulties?
simple command:
get-aduser -filter * | set-aduser -mobile $null
or only enabled user:
get-aduser -filter {Enabled -eq "True"} | set-aduser -mobile $null
