windows phone 7 will not sync with exchange 2010

I recently migrated/upgraded my exchange 2007 server to exchange 2010.  The exchange 2007 server has been removed and everything is ok, but...  All of our mobile phones are syncing except the two Windows Phone 7 devices in the company.  I bought and installed a new certificate for the new server from Verisign.  We have SSL turned on and the Andriods & iPhones work fine, but the Windows Phone 7s give an 80072f06 certificate error.  I have found several articles and most refer to domian admins which neither of the users are.  I would appreciate any ideas on this.

login to webmail, save the certificate by clicking the padlock ssl secure symbol to local HDD, then email (may be via gmail) those certificates to your phone. Open the email and click on cetificates attachment, it will install the certificates on phone and you will be able to configure your exchange a/c then, tried and tested it works

#AmitKhilnaney  I do not see how to save the certificate?  I can look at all the details, but I don't see a way to save it.  (IE9)  The copy to file option is greyed out under details.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

I tried manually installing the certificate on the phone, but I get the same error.  This is a brand new certificate from Verisign.  How can it not be trusted on Windows Phones?  Even after I maually installed the cert on the phone, it didn't work?  Where do I go from here?
 

Thanks!

Worked with Verisign and had to install new intermediate certificate for backward compatibility as Windows Phones do not yet support Verisign G5 certificates.  Verisgn knowledgebase article SO8227.
