How to remove an orphaned user from Exchange 2000

I have a client that is using Exchange 2000 SP2.  A recipient mailbox, Adrian Garcia, was deleted sometime ago and does not show up in ADUC nor System Manager.  When a user sends a calendar invitation to a distribution list, all members of that DL upon responding get this message:

Your message did not reach some or all of the intended recipients.

      Subject: Accepted: Meeting
      Sent: 12/7/2009 12:13 PM

The following recipient(s) could not be reached:

      Adrian Garcia on 12/7/2009 12:13 PM
            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.

I assume that the recipient/user is still orphaned in AD somewhere.  How can I clean out that record so that the recipients/responders don't get the NDR anymore?

Thanks

Try checking the membership of the DL to see if the user is still listed there, if so delete him from the DL.
Check the mailbox retention policy.  Check whether it is set to not delete mailnboxes unitil after a backup, if so, either do a backup, or change the setting.  Also try reducing the retention period to 0 and see if the mailbox goes.

Another possibilty here is that someone has a forwarding rule set up to forward the email to that address.  Check the accounts in the DL for such a forwarding rule.

That is classic delegates. The user who is getting the invite or whatever still has the user listed as a delegate. You need to remove them from the list of delegates manually.

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Sorry, it turns out there are no DLs in play here.  She sends invites to individuals and they all get NDRs when accepting/declining/tentative.

DCMBS:  No mailbox retention policy.  Not set to delete mailboxes until after backup.  Retention period is already set to 0.  

Mestha:  Her Outlook settings do not have him as a delegate.

She has no forwarding rules in place.  His mailbox is not visible in System Manager even when Mailbox Maintenance is run.  Could it just be an orphaned object in AD schema?

What about contacts ? Do you have a contact for this person ?

Have a look to this thread : http://www.petri.co.il/manually-undeleting-objects-windows-active-directory-ad.htm
Did you see the mailbox ?

Check the accounts in ADUC under exchange delivery options for any forwarding rules.

BCN_AdminAuthor Commented:
leakim971: No contact.  Can't see the mailbox.

DCMBS: There is no account for that user.  Is there a way to search AD for his name and remove any orphaned records?

Can you run:
ldifde -f ExportUser.ldf -r "(objectclass=user)"

from a Server that has the Active Directory tools installed.
Once output open the exportuser.ldf file in notepad and do a search for the old username

If it doesn't appear in here it's not in Active Directory and must be configured as a delegate on someone elses mailbox.

It won't be an account for that user,  It will another user who has been nominated to receive email addressed to that account.  You will have to check delivery options for each account list in the Distribution List.  As it is being triggered by a deliovery sent to the DL it could be any account in the DL.

DCMBS: I see where you are going, but there is no DL.  She adds each address one at a time to the message and sends it.  I may have to connect to each Outlook client to check their Delegates.  

Any other ideas if that doesn't work?

Glen KnightCommented:
One of the users she is sending to must have a delegate.

Get the user to send individual messages and see which one bounces back with the NDR obviously leave a few minutes between each one or send them all with different subject headers so you know which one bounces back.

demazter:  I agree and am waiting for the user to respond with available times.

We resolved the issue.  It was a delegates issue that was invisible.  The user mailbox in question was, in the past, a delegate on the sender's mailbox.  Once the user was deleted, it did not show as a Delegate.  Simply adding a Delegate and then removing it cleared up the issue.
