I don't think this was the question of the original poster. He wants to selectively remove a single service (e.g. calendar).
There is no function on BES to achieve that, but why not (as the user leaves the company) go into his Outlook, delete all the calendar items, give it some time to sync and then switch off sync for the calendar.
Same for mail or contacts.
