I have a BES server working with Exchange 2003.
Recently, I've setup a new Exchange 2007 and plans to migrate the users over to 2007.
However, after I migrate myself from 2003 to 2007 server, the Blackberry services fails to work:
meaning, my emails are not forwarded to my BB, and I cannot send emails out from my BB.
Is there any other steps required for this?
