NDR Code: 5.1.7
First Available: Exchange 2000 Service Pack 2
Possible Cause: The sender has a malformed or missing mail attribute in the directory structure. The Transport categorizer cannot deliver the mail item without a valid mail attribute.
Troubleshooting: Verify the sender directory structure and determine whether the mail attribute exists.

* Kindly check user attibutes from adsiedit.msc; is this mailbox was moved from another server ?? or was it migrated ??
