I have a Blackberry Enterprise Server 4.1 in a Exchange 2003 environment running on Windows 2003 AD. I have multiple exchange servers in different child domains. In the US child domain where the BES is located, all my BB users are fine. I have a user in amsterdam who can receive mail but cannot send mail from his BB. His mail server is in the UK child domain. I set all the permissions for send as and receive as in the ESM UK mail server and the information store. I then when into AD, advance view and added the same permission to the users profile in AD. I restarted the routing and dispatcher service on the BES but he still gets the red X when trying to send mail. Please help.
