We have three Exchange servers from three domains in one site running over a Wan. One server (server 2) constantly reports warnings every 10 mins or so regarding a problem with the default server (server 1). I’ve looked at technet and it specifiesthat the override tab should be checked. But we do not use an override since all domains have two-way trusts. Emails works, but occassionaly Server2 stops sending/receiving emails from server1 and the only thing reported in Event viewer is the abovemessage. I’ve checked the obvious like site and configuration permissions and they look in order. Any ideas?
