I have the following on my local network.
Server DomainA -> Small Business server 2003/Exchange 2003
Server DomainB -> Windows 2008 R2/Exchange 2013
Clients Domain A -> Windows XP/Outlook 2003
Clients Domain B -> Windows 7/Outlook 2007/2010
Problem: I want clients from DomainA to log into Exchange on DomainB on the same local network.
I need to know how to setup the DNS on both domains and the certificates on the DomainB Exchange server
to accept the connection from the PC on domainA. All connections from clients on domainB to server on domainB
work correctly but when adding accounts to Outlook 2003/2007 on domainA clients I am getting certificate errors.
I have purchased certificates for mail.domainb.com and autodiscover.domainb.com but I dont know how to get
the clients on domainA to recognize those external URL's of the exchange server (with the certificates bound to them) from the internal network. Hence I get domain errors.
I am getting issues when a client on DomainA tries to add an Outlook mail profile to connect to the Exchange on DomainB
Any suggestions on how to set this up?
thanks
