I am not sure if this is an AD or an exchange problem, so please move if necessary. An old user account is inlcuded on meeting requests sent from current users, because the account has been delete a "message could not be delivered" is returned to any meeting request. The old manager was deleted from AD and their Exchange mailbox removed. We did not realize the account was still setup to receive meeting notices for some users in their department. Now when those users send or receive a meeting request, a notice is generated that some recepients could not be contacted and sent to the meeting requestor. Is there anyway to clean up the old account? I cannot find the old account attached to their AD or Exchange accounts.

Remove the stale delegate, or run outlook.exe /cleanrules. Accepting or denying a meeting request causes a "5.1.1" non-delivery report in Exchange Server http://support.microsoft.com/kb/312433James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

If the account's not in the AD they'll see the old account's SID in the list. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
