  • Renamed user problem surfaces after 5 years

    Hi guys. Odd problem here.

    ~5 years ago while we were on Exchange 2000 a user (lets call him Bob) left and was replaced. Instead of creating a new account, the IT guy just renamed Bob's account and gave it to the new user (call him Joe). Everything worked fine until recently. Now occasionally when any internal user e-mails Joe they'll get the following
    The following recipient(s) cannot be reached:

    Bob on 10/4/2007 07:40 AM

    The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.

    <exchange.mydomain.com #5.1.1>
    What's interesting is that even though the sender will get a NDR, Joe will still get the e-mail. Also it doesn't happen every time you send him an e-mail. It's very infrequent making it tough to debug.

    We've been on Exchange 2003 for the last couple years and I can't find any trace of Bob in Active Directory. The account seems to be properly configured for Joe.

    I've never run into anything like this. Any ideas?
    Thanks in advance!

    Not sure how to fix this, but honestly, I'd slap the "IT guy" who did this! Always disable term'd employees' AD accounts, not rename.

    AFAIK, the only solution may be to delete / recreate them in AD and/or Exchange, but I'd wait on the response from someone more experienced in this before you go ahead and make any changes.

      If it wasn't so cliche for an IT guy to criticize his predecessors I'd have more to say about this guy. Suffices to say this isn't the first cleanup I've had to do.

      Yea, that's what I'm thinking but I want to exhaust all options before I do.

        Does the originator pick "Joe" from the GAL in Outlook, or are they using the AutoComplete to pick his name?

        If it's from the GAL, well, sorry, got nothing. If it's autocomplete, tell them to start typing "joe" and hit delete when autocomplete suggests the address. Then pick Joe's name from the GAL and resend.

        (re: renaming vs. copying a disabled account) - old NT4 administrators renamed accounts, maintaining SID history and permissions on file shares, and MS best practices (at the time) suggested it.

          I wish it was that easy. They're using the correct e-mail address. We have one leftover Exchange 2000 server that we're FINALLY getting rid of and I'm hoping it's something related to that server.

            That looks like a delegate problem. It could be a stale delegate somewhere in he domain. Does the user use delegates at all?

              Yea that's exactly what it was. There weren't any delegates in his list but the grayed out "Send meeting requests and responses to my delegates" check box was checked. I added a delegate user, unchecked the box, and removed the user and so far I haven't seen another NDR. Sweet.

                  Well technically I had it solved that morning but I gave him the cred anyway.
