Hi all, We have a strange problem with an Exchange 2007 set up at one of our customers. It all appears to be running ok in general except that meeting requests sent to one user are being forwarded to a dsitribution list automatically. I have checked the users Outlook profile and there are no forwarding rules or delegates set up in the system. Exchange Message Tracking has the following event after a meeting request has been delivered: EventID: Expand Source: RoutingRecipientStatus: 250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded It then sends it to all users in the distribution list. Anyone have any ideas where I should be looking for this issue? OR how to resolve it? It's completely baffling me!!! Regards,Daiablo
