I'm having an issue configuring Outlook to create a profile for our new exchange environment running 2013. The environment consists of 2 CAS servers and 2 Mailbox Servers. When Outlook launches and tries to create a profile it fails to be able to connect to the Exchange server and keeps prompting for credentials which are being rejected. I have no issues logging in via OWA. The domain name is domain.net and I'm using mail.domain.com for everything for Exchnage. I'm thinking something with autodiscover possibly but cant seem to determine what is causing this issue.
