I'd like to find a recent document (or recent posting I've overlooked) that objectively compares/contrasts BES vs Exchange 2003 SP2 ActiveSync. Thanks.

BES works...

Useful...thanks for your insight

Keep in mind that that study was done by a MS partner and sponsored by MS.

The study does go into speculative territory when talking about additional support costs for a BB setup. I have a dozen BB users and 1 BES. I have never spent more than 1 hour per month on support, and usually it's hold time with my network provider to get authorization to send an old unit back for exchange.

BES is a secure, reliable proven platform. The MS offereing is new and not all WM5 devices support it.
