Can you follow my guide here: https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2300-Outlook-continually-prompting-for-username-and-password.html

First make sure you have SP3 installed, then try the kernel mode authentication.

If that doesn't work, do you have a self signed or 3rd party certificate? The domain name, is this one you recognise? Is it your own?
