Thanks a lot.
Exchange doesn't talk to BES. Exchange has no idea BES is poking it all the time like a hot poker. BES scans the user mailboxes for changes and then performs the necessary actions to get them to the handhelds.
BES 4.1.6 MR7 x 2 : 2,300 users and growing
Exchange 2003/2007/2010: 35,000 users and growing
