Exchange 2003 Network with Outlook 2003 Clients in Native mode single domain with Global Catalogues in every site.
The problem is a certain group of users are receiving emails 4-5 days later after being sent.
One user for some reason received 2000 emails within a 24 hour period but just went away for some unknown reason. It was the same 5 emails.
The erro code was (Server error or configuration error, check your settings) when these dups came in.
One person suggested that it had something to do with the resolution of the Distribution List that the sender is sending to. We converted the group to Global so it can replicate with the global catalogue but don't know if this is the solution as of yet.
Does anybody have any ideas of what can cause these problems?
