Hello,
This is probably something very simple that I'm overlooking. We recently let our primary System Admin go and he was the one that did the majority of the work setting up our new Exchange 2013 server so I'm uncertain of what for sure has been done but I'm hoping someone here can help out.
Here's the situation:
Brand new domain (Call it DomainX) with a Brand new Exchange Server (ExchangeX) running both the mailboxes and Client Access roles.
Old Domain (Domain Y) with Exchange 2003 (ExchangeY).
Two different IP Ranges as well. Range 10.x and Range 192.x. DomainX has all servers on Range 10.x while all servers and clients on DomainY are on 192.x.
PCs on DomainX and Range 10.x can see and connect to ExchangeX immediately and flawlessly.
PCs on DomainX and Range 192.x can connect to ExchangeX by using the Outlook Anywhere setup.
PCs on DomainY and either Range get the error that ExchangeX is offline or not available.
PCs on both Domains can connect to ExchangeY with no issue.
PCs on both domain are able to ping ExchangeX by name and IP address successfully.
So what am I overlooking? How do I get PCs on DomainY to connect to ExchangeX?
