I have a windows 2003 network and am running exchange 2003. When I add a new user to my AD, my exchange box is not adding the mailbox for that user? It was working fine, and then stopped updating. I looked at SM and the recepient update service and that looks fine. Under admin groups, servers, the GC and DC are pointing to a different DC but it is in the Domain and should be fine too. Any suggestions from anyone? My email is firstname.lastname@example.org Thank You!
