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 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 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?
