I have an odd problem which I just can't see to figure out for the life of me! I'll give the scenario below:
- Exchange 2013 Server OWA doesn't work using the FQDN of mail.server.com unless done from the exchange server itself.
- Browsing to the IP loads the OWA page
- DNS all resolves to the correct IP address and NS lookup also works correctly.
- Works perfectly fine externally
If everything wasn't resolving as expected I'd definitely blame DNS but due to the odd nature of all the records resolving as expected I'm not too sure.
Any help would be appreciated.
