What happens when you try to send as the BES account? Do you get a red X? If so, open the message and scroll up - what is the Message Status?
Our BES has no restrictions on sending mail. If I go to compose a new message, I can send as Default or the BIS account. When I look at the Desktop Service Book [CMIME], the UID is the BIS account. The Desktop [CICAL] looks the same way. I had the BES admin re-send the service books, but still nothing. All changes I make in Exchange will show up on the BB, but not vice versa.
I did notice that all messages coming from the BES server say Received Using: Unknown.
