I am running Exchange 2003 on my end and across the WAN is another Exchange 2000 server on my domain. I have OWA enabled on the 2003 server, however any mailboxes that are on the Exchange 2000 server can't access OWA. It asks for a username and password, once that is imput then it fowards a request to the Exchange 2000 server and doesnt open up OWA from the Exchange 2000 server. Anyone know how to configure OWA so that it will pull up accounts from both mail servers that are connected thru the WAN?
