Exchange 2003 Mailbox Recreation Problem

I am running Exchange 2003 SP2 and Outlook 2003 clients in a Windows Server 2003 environment.  In dealing with an oddly-behaving AD user's mailbox, I performed the following: used Exmerge to export this user's mailbox contents to a .PST file which I stored on a different server; deleted this user's exchange setup from their PC and Outlook client; from ADUC, I deleted this user's mailbox using Exchange Tasks, created a new mailbox (using the same alias) after it said this one was deleted, and then tried to reimport the .PST contents to this recreated mailbox using Exmerge again.  One thing I noticed when going through the import process, though, was that the directory name listed for this user in Exmerge now had 8 numbers attached to the end of the directory name (i.e. display name: john doe, directory name: jdoe12345678) and so the import failed due to the .PST file being jdoe.pst.  So, I exited Exmerge, changed the .PST file's name to jdoe12345678 and then was successfully able to import the contents into the mailbox.  The contents are there, but now we have NDRs to this user as I believe Exchange is thinking this user's email address is jdoe12345678 even though when I type jdoe in Outlook it appears to correctly resolve to John Doe before sending the message.  If I reply to a message from this user, the message gets through no problem, or if I send a new message from an outside account or an interface where Outlook doesn't autoresolve the address, it also gets through no problem.  I deleted the autocomplete entry from my Outlook that would pop up jdoe12345678, but it doesn't seem to help matters.  How can I correct this entry/mailbox?  I suppose it's probably going to involve deleting the account/mailbox again?  Sorry for rambling...

If your did not run the purge option in the Exchange System Manager the old mailbox will still be in the STORE (waiting to be re-connected - IE accidental deletion) or until the IS clean up tool runs and deletes any disconnected mailboxes. Exchange found Joe Doe and added a new JOE DOE 2 mailbox. That is why the weird name was needed to import the PST.

As far as the NDR:
Any email client that auto completes will have the old internal exchange email address in the nickname cache  Outlook 2003/2007. Outlook picks names from the auto complete before using the GAL. In addition, Outlook 2003/2007 uses the local offline address book, which will have the old email address until the offline address book updates on the server. You can wait for offline address book update service to run (typically at 2:00am each night_ and that will remove the old users email address, system x400 and SMTP.

Alternatively, if you just have old, outdated entries on your nickname list, you can remove individual unneeded entries. To do this, from the New Message window, type in the first letter of the persons nickname. Scroll through the entries on the list using the arrow keys, and press the Delete key once you get to the entry you would like removed.

I ran the purge after I found three mailboxes with username jdoe.  Two had what looked like the old, full contents, but one had 2KB.  I assume this last one was the new one with the weird name.  So, I reconnected one of the two "full" boxes and purged the other two.  However, I'm not sure what was reconnected.  Last night I tried to run a restore of that mailbox from tape backup but got an error that it couldn't be restored because that mailbox didn't exist on the store.  I think I may have royally messed this user up.

I ended up deleting this user's entire AD account and starting over after making sure to purge all references to mailboxes.
