I have been moving mailboxes from our exchange 2003 to our exchange 2007. As a test I used my account. When moving the mailbox I received errors so I decided to backup to a PST. I backed up to a pst then removed my mailbox from Active Directory, then recreated my mailbox, and imported the PST. When some users send me mail it tells them that the user account does not exist at this organization. This happens when using the organization address and the default address.
Example: firstname.lastname@example.org - does not work
email@example.com does work
firstname.lastname@example.org does not work
What am I missing. I have successfully moved other mailboxes without problem but mine is the only one causing trouble. Any helpful suggestions on what to try would be great. Below are things tried.
moved mailbox back to exchange 2003 - still could not receive from certain users
moved mailbox back to exchange 2007 - no change
added smtp address for @servername.bankrcb.net
disabled second network interface on exchange 2007
