Whenever a specific user receives a meeting request and chooses to accept it and send a response. A second disabled user also accepts and sends a response. Before deleting the disabled user, I want to make sure I clear up this issue. How can this happen? I don't see any email forwarding occurring and as far as I can tell no delegation or send on behalf of, sorts of things. What else could cause this behavior? Exchange 2003 - fully patched. Thanks.

Delegate. I expect the first user has the second user listed as a delegate. Check on the delegates tab in Outlook. Simon.Simon Butler, Exchange MVP. http://blog.sembee.co.uk , http://exbpa.com/

Unfortunately, upon checking, the user is not listed under delegates. There also wasn't a rule that forwards any email to the disabled user. Any other ideas? I am stumped.

You can use MFCMAPI to delete the corrupt Delegate rule from the mailbox. -> Go to Session->Logon and Display Store Table -> Select your profile -> Select Mailbox -> Expand "Root Container" -> Expand "Top of Information Store" -> Select "Inbox" -> Right click on Inbox and select "Display Rules Table" -> Under "PR_Rule_Provider" column delete the entry with display name "Schedule+EMS Interface" -> Close MFCMAPI.Arun Kumar | MCSE:W2K3 + Messaging | MCTS:Exchange 2007 | MCTS:OCS 2007 R2 | ITIL-F V3
