I'll start off with this is my first exchange 2013 install.
I have a single server environment. I have the AD running and exchange working, incoming and outgoing, perfectly with OWA. I can not get my outlook 2010 clients to connect to the server. When I run auto-discovery outlook establishes the connection and finds the server but then I get a login box for my servername.corp.domain.com but no matter what I enter it fails.
Inital email addresses were user@corp.domain.com, I added and sent the reply addresses to user@domain.com for mail flow.
Any thoughts or direction would be appreciated.
