We have the weirdest problem with Outlook 2003 clients in our network. We run Windows Server 2003 SP1 with Exchange 2003 SP2. All clients run Office 2003 SP2.
A while ago we deleted a user who left our company. Now we have several users who appear to have some kind of connection with that old user which doesn't exist anymore.
When those users create a meeting request and invite other people to that meeting, a undeliverable mail is sent to the users who accept that meeting request. The undeliverable states that the user <deleted username> could not be found in the organisation. The meeting request itself, including all the users who are accepting it, works fine.
But that deleted user account, of which our Exchange server claims that it couldn’t be found, wasn’t even invited to this meeting! Nor is she in any of the groups invited.
We already ran a defragmentation and a consistency check on the Exchange database. Neither of them encountered any problems.
Please help us with this very strange and annoying problem
