Here is an article on <a href="http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB11036&sliceId=SAL_Public&dialogID=69199896&stateId=0%200%20692%2001325">blocking BIS </a>. I don't have a similar article for iPhone unfortunately. One thing you can do is turn off active sync for all users and then enable it for only those who are approved, but that does not stop them from using OWA on the iPhone instead. It just stops active sync.

If u lock the BIS at the firewall then they will never connect. Just block BIS IP's incoming ports 80 and 443 for SSL.

If you live outside the United States, by submitting your email address you consent to having your personal data transferred to and processed in the United States.
You can do that as mentioned by Rechil, but another quick way, that is if you don’t use WEBMAIL you can disable OWA at the user mailbox level and he wont be able to connect to his mailbox with any mobile device as BIS and Mail For Exchange uses OWA on Exchange.
