We received our .CER file for our Digicert SAN certificate and have successfully installed it on our new Exchange 2010 CAS server (this will be coexisting with our Exchange 2007 organisation until we've moved all of our 2007 mailboxes over). We are attempting to assign services to the new certificate using the Exchange Management Console wizard, but Exchange will only allow us to assign the IIS service to it. When attempting to assign the SMTP service, the process fails and the wizard reports the following error:
One of the services you've selected (IMAP4, POP3, SMTP, IIS, UM) isn't installed on this server. Please check which services are installed on the server and try again.
We've searched the web extensively for a resolution but have been unsuccessful. Any ideas?
