Hey Adrian,

The name of the server specified in the Certificate should match the
FQDN of the OWA you're using. Is this the case? E.g. if the name on the
certificate is you should be accessing OWA using rather than say

Regarding the authentication, I'm guessing that you don't have Forms
Based Authentication enabled on your Exchange Server, and IE is
authenticating automatically for you because you're logged on to a
domain. Once you enable Forms Based Authentication, you'll be prompted
for your username and password by an OWA login page.
