I had to remove two domains from the SAN list in our GoDaddy SSL certificate for our mail domain. The question I have since I received the new verified certificate is can I create a CSR from a renewal request on the Exchange server even though it will be missing those two domains? Or do I have to create a completely new certificate request? If so, what is the best way via PowerShell to get all the information to fill the new certificate?
