The Doe's are former employees whose mailboxes and domain accounts have been removed a while back. When I check the dist list in the exchange administrator, I do not see their names listed...

Does anyone know why a particular user will get NDR's for former employees (deleted accounts) . as far as I know, this user is the only person having this problem.

Thanks!

If you've removed the recipient from exchange then the most likely expaination is the user has created their own DL with john.doe in it.
