I have problem with synchronization my Calendar on BB Torch 9800 with Exchange server via BES.
This problem is new after migration from MS SBS server 2003 to SBS 2011.
When I insert in Outlook new appoitment, BB synchronize with Exhange corectly. But, when I try change this appoitment on BB (e.g. Time or Date), this appoitment doesn't synchronize with exhange. On BB I have new time and in Outlook the last.
I try delete user from BES, factory reset BB and make new connection. But all is all right - mail, contacts, tasks, only calendar have the some problem.

Have you, please, any idea or some reference?
I am already desperate

Thank you....
