Hiding Mobile Number Attributes from Outlook GAL for Selected Users

Question

Hello everyone,

We have a requirement to hide active directory attribute mobile number from Outlook address book for selected users only.

One solution we have found so far is to deny permissions to read mobile number on that user object on active directory. It seems to be working only when denying permission for Authenticated Users. We still want some security groups (admins / service desk) to view the same attributes. User mobile number still appears if all other security groups are denied permissions.

Any other work around would be highly appreciated.

Hello,

My suggestion would be to move the Mobile Number attribute to Extended Atribute (for example "extensionAttribute1") as GAL will not look into Extended Attributes. I propose a simple script:

$users = get-aduser -Filter * -Properties *|Where-Object {$_.MobilePhone -ne $null }| Select-Object Samaccountname,MobilePhone

foreach($user in $users)

{

set-aduser -identity $user.Samaccountname -add @{otherMobile=$user.extensionAttribute1}

}
