Think I have resolved this issue.
Found on the users active directory entry that the email
address specified was a hotmail.com account.
When I changed it to be an internal address, the user was
able to receive external messages again. No more error
messages to the senders either.
Since I'm new to Exchange Server, I'm guessing that this
happened because the server is set to prevent relaying
without authenication, so when messages came in for this
user, it checked and found the hotmail address and
wouldn't allow the external sender to pass thru to deliver
Hope this helps someone else.
