I have three users, A, B, and C. A is the primary boss, B and C are assistants. User A setup his outlook somehow so that when he gets a meeting request, it sends a meeting request to user B and C to accept the meeting on user A's behalf. User C is no longer with the company, we deleted the mailbox, and eventually the active directory account connected to that.Now when any user in the organization sends a meeting request to user A, user B gets the message still.. near the top it says "Received for User_A". However, whoever is organizing the meeting gets a failed delivery alert for user C.How can I clean up these messages?EDIT: If this info helps: We migrated from Exchange 2003 when 2007 was released.

I would start with User A's mailbox and look for any rules that may be configured on the outlook client to foward meeting requests to the two users.SF - MCITP:EMA, MCTS

Yes indeed, there might be some forwarding rules configured. If you can't see it in Outlook Delegates settings, you may need to remove it with MFCMapi. Similar Thread for MFCMapi operation:http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/8ef3fa80-7692-4402-b788-39774a2e81e9Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

Oh yeah I've been through ever delegate setting I know of on both client and server and couldn't find anything, I'm sure there is some data somewhere that needs cleaning.Do I use MFCMapi on the client or server? I've been reading several posts but they don't state where to launch it.

You need to run MFCMapi on the workstation where you have outlook profile configured.Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

Ugh! Having the same exact problem on our Exchange 2007 server. It's like the deleted account is still registering on the server somewhere, although it's not listed anywhere. I don't think it has anything to do with forwarding rules. I think what the problem is, is on the server (actually set on Exchange 2003 and then got transfered on the upgrade to 2007) User A "The Boss" had User "B" the assistant set to having Send As permission set at the server, not on Outlook and then User B's account got deleted, but somehow it's still a ghost in the system

did you ever get this sorted? we're having the same issue...
