Exchange meeting request - Invite not reaching some or all of the intended recipients


We run Exchange 2003 and Outlook 2003.

We have some users that when they send meeting requests they get a response back from users that weren't included on the invite and no longer exist in AD.

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

The following recipient(s) could not be reached:

      username on 1/1/2010 2:42 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.
            <EXCHANGE.domain.Local #5.1.1>

I have checked AD the users no longer exist in AD and they werent included on the meeting invite.

Does someone knows what could be the cause of this problem?

Thank you.

To rule out a common issue, are any of the invitees group/distribution list? If so are there members in that list that are disabled or no longer part of the AD? Also check to see if you have any Query Based Distribution groups that are being invited as well.

I have checked that already and the user said that sometimes is a distribuition lists and sometimes is just to individual users.

I have also checked if the user had any type of delegation in Outlook "Delegation TAB" or in AD but haven't seen anything.

Also the user mentioned that she never had any of those users with delegated access.

You could track the message in Exchange System Manager, by tracking it you can see who it was originally addressed to and follow it's path to the users mailbox.  You have to have Mailbox Tracking enabled....

Open Exchange System Manager, Drill down to the Server Object -Right Click and Click Properties. Make sure "Enable message tracking" is ticked.

If it is you can check the logs now, if it was not then you will have to resend the bounced message as it was originally sent.

To Track messages:

In Exchange System Manager expand Tools by clicking the + next to Tools -> Click Message Tracking Center.

Enter in any of the following: Message ID, Sender, and Recipients -> Click the Server button and select your Server then click "Find Now"
