Disabling mobility services for Active Directory users

I was talking to James the other day about using mobility features with users  He wanted to be able to disable certain individual user accounts access to all Mobile Services provided by Exchange 2003 without going to the Exchange Features tab in the account properties in Active Directory.  He wanted to disable or enable access to ALL users within an OU or Domain without going to each individual user account?  He asked whether there’s a script around that can do it, but couldnt find one.

I had a look around, and asked a few colleagues and came up with AD modify which will allow you to do this.  Have a look at this article written by Henrik for a step by step article on how this is done.  Seems like this will save James quite a bit of time (he works in a rather large organisation).
