Fresh install of SBS 2011 and trying to access OWA externally and externally. Page displays but I am unable to login using domain\username or UPN or username. I have setup Outlook clients and able to send/receive. Checked authentication methods and made sure they are installed and basic, windows, and digest are installed. I keep getting a loop at the login screen.
What do you think could be going on?
Thanks for your help.
