I can send from exch2010 to another exch2010 account, so I assume I do. The problem is occuring when trying to send from an exch2010 blackberry to an exch2003 email account.
The new BES 5.0.2 is using a new service account that differs from the one the original BES was installed with, but I thought we got the permissions sorted out for the new account on exch2003 Friday. Maybe not.
