Outlook 2010 - Security Alert

We have a newly built Exchange Server. Couple of my users are having this particular issue:

Both the users are running Outlook 2010 Home  Business 2010.  A "security alert" screen is popping up with the following error:

"The name on the Security certificate is invalid".

I can view the certificate and install it ...it says import successful. but it pops up again. Is there anything wrong with Exchange server settings or Outlook 2010 itself? Please advise. Everyone can use OWA fine. Also, Outlook 2007 users are not receiving this error.

Thanks for your advice/help.
