I have a single Exchange 2010 server running the mailbox, CAS and HUB transport roles. Things have been working for about 2 months until we started adding Outlook 2010 clients. We started getting SSL mismatch errors on the clients. Basically that problem boils down to the fact that we are not using a SAN certificate and the internal and external FQDN's don't match.
While trying to fix that problem we are now unable to connect to the site with Internet Explorer on the Exchange server it self with the FQDN or from other machines on the network. (Using another browser like Chrome allows us to access the site just fine?) We can access the site externally and with clients connected to our VPN.
In looking around I see that within IIS our Default Website has the globe with a question mark on it. So I started looking around in IIS. If I click on the OWAfolder under the default website and right click Authentication and choose Basic Settings, I try and click the Test Settings... button I get an error. "There was an error while performing this operation. Details: Invalid Application Path"
I've been all over the place on this one and it's starting to get really frustrating. I just want my OWA back to operational for my clients. I can deal with the original SSL cert mismatch problem later.
Thanks for any help or points to get me moving on this.
