New SSL certificate installed on Exchange 2010 but outlook give security alert for expired certificate

Dear All,

I have renewed UCC SSL Certificate from Godaddy and installed it on Exchange 2010 successfully. I tested with online ssl tools and its verified.

However, whenever i open outlook 2007, i get security alert that ssl certificate expired.
I try to delete that certificate using its thumbprint on Exchange Shell with no hope. It says didn't find a certificate with that thumbprint.

I try to find that in registry. Its even not there.

Please give me some solution.

Thanks
