The messaging environment is Exchange 2003 SP2. BES1 connets to one Exchange server and BES2 connects to another. I have not seen any other lose in functionality since the merge other than this issue.
Unfortunately, this case is already within the BlackBerry Support Escalation team and they have run into a wall. That is why I am posting here to see if anyone else has any fresh ideas.
NOTE: I did create a new db using the CreateDB.exe tool I then performed the other steps mentioned above.
If you have performed a DB merge before and can confirm your User ID's have changed and you are not have this problem, I would like to hear about it. Support is stuck on that being the specific cause and if I can show them that is not the case in other implementations, then maybe I can get them to look at other areas.
