Dear All,I have a problem with outlook 2003 calender with exchange 2007. User A send a calender request to user B then User B automatically forward this request to USER C which is no longer exist. So that User A get a Non delivery report from User C account (Which is Already deleted from the server). I think somewhere user B share or delegate his calender with user C. But user B said that he did not do anything. Please help me.ThanksMahatabRahimafrooz Bangladesh Ltd.

Please see:http://support.microsoft.com/kb/909638Members of your organization may receive a non-delivery report if your delegate’s mailbox object is removed from Active Directory before you can remove the delegate in Outlook 2003

Dear Allen,Thanks for your proposal. I already checked before write in the blog. There is no delegation and rules in users mailbox.Thanksmahatab

Ensure there are no rules or forwarding on the account for User B. If not export all his rules in Outlook and start Outlook with the /cleanrules switch. If that doesnt work, use mfcmapi to find any rules that may forwardinghttp://support.microsoft.com/kb/924297http://www.codeplex.com/MFCMAPI
