Question : Exchage 2010 OWA can't log in

I recently created a new Windows Server 2008R2 domain with a single Exchange 2010 server. I am in the process of transferring users from an old SBS W2K8 domain to this one. I exported the Entrust public certificate from the old SBS server and imported it into the certificate store on the Exchange 2010 server.

The URL is remote.gssec.k12.in.us. When I go to https://remote.gssec.k12.in.us/owa the IE8 browser gives me the page warning me that there is a problem with the websites certificate. If I choose to continue to the website, I get the Outlook Web App login page but when I put in my username and password, it doesn't recognize it.

If I view the certificate, it shows the self-signed certificate that was generated when I installed Exchange 2010, specifying the name of the mail server. The Entrust certificate is not being picked up.

I assume that the reason I can't log in to OWA is because of the certificate problem.

Any ideas as to why the imported Entrust certificate that worked just fine on the SBS 2008 / Exchange 2007 domain does not seem to work here?

Can anyone confirm that a valid certificate is needed before I can log in or is my login problem not related to the certificate?

Thanks

Dave
