I am looking in to using a self published SSL certificate in order that we can start using Exchange ActiveSync at one of our offices. I've read the FAQ at
which explains things pretty well, except for one point.
At the point where you choose the certificate common name, the article says you need to pay extra special attention to the common name, as it reflects the FQDN of your mail server. He then adds a note about ISPs often setting the A record.
However, our A record points to our spam/virus/content filtering service, who then forward mail to our mail server by IP, not hostname. We therefore don't have an FQDN for our mail server. At present I have a test device accessing ActiveSync by IP address, and all OWA access is by IP address.
My question therefore is, given that I don't have an FQDN, what should I use as the Certificate Common Name? Does it matter in this context, if all OWA & ActiveSync connections are made using an IP address and not a hostname?
Thanks in advance.
