I'm trying to access subscribers mailboxes on Exchange using Outlook Web Access. This works fine on two clusters but the third has some resolution issue. When trying to access the mailbox through OWA, I put in the URL http://10.10.10.54/exchange/alias/inbox
The username/password box pops up normally. But, when I put in the DOMAIN\alias and password, it will say, at the top, "connecting to unityservername.companyname.com" After several seconds, it will fail and the url in the address box will be http://unityservername.companyname.com, not the Exchange server name. It appears to be some kind of resolution issue. But, the Host flies on Unity and Exhange are correct. Unity points to Exchange for DNS and Exchange points to another DNS server that I don't have access to. All other services work. I pointed the Exchange server to itself for DNS and still got the same thing.
I even tried access on the Exchange server itself, got the same thing.
Is there some other place to look for resolution? Or could it be something different?
