In IIS on my exhange server, when I go through the new certificate setup everything goes well until I need to select a certificate authority. For whatever reason my exchange server does not see my CA, its not an option to select in the drop down. How can I get my exchange server to see my Certificate Authority? There are no network or security reason that would prohibit this. The CA is install correctly and all the services are running. Any help on this would be great.
