I have recently set up an Exchange 2003 server on a 2003 domain controller. Initially, I was able to send mail internally between users, however, I am now unable to do that. I start a new email, address it etc etc, send it, and it disappears from the Outbox, but never arrives in the inbox. Any ideas?
Also, for some bizarre reason, the administrator is denied access to everyone else's mailbox, and I know that a domain admin should have access to anyone's inbox.
