Hide some user contact information fields
We would like to allow users to put a mobile phone number into their contact information so they can use it for password recovery. We know how to accomplish this, but we want to find a way to hide their mobile numbers from the other users. Right now the mobile numbers are on full display in the GAL.

This is a real issue for our ORG. we use the mobile number for 2 factor and password resets but having the numbers published in the GAL is causing issues, with lawyers involved(harassment case) i would think in today's environment this would be i click box some where blocking from the GAL. We all need to use our phone for productivity but the 2000 people i work with don't need to know my number and I don't need to know theirs
Agreed, this use to be available in the templates editor on previous versions of exchange on premises.
