Take a look at :XADM: Event ID 11 Logged in the Application Log (Q222066) I had this same issue, and I did have a legitimate problem where I had two mailboxes with the same alias, so everytime the script would hit that mailbox I would encounter an error, and the script never worked. _____ -----Original Message----- From: Central Techie [mailto:exchangelist@xxxxxxxxxxxxxxxxxxxxx] Sent: Monday, May 13, 2002 1:31 PM To: Ohl, Julie Subject: RE: [exchangelist] RE: Auto Accept Meeting in Exchange 2000 w/ Outlook 2002 clients I know why they're not accepting now, but don't know how to fix, maybe you have some ideas. I am getting errors in the application log saying: "A fatal error (0x80040111) occurred in an IExchangeEventSink while processing message [Subject = "Test"]." Any ides what might be causing the error? I copied exactly what your script had.
