I found the solution at http://alittlestupid.com/2005/11/23/view-ssl-cert-from-terminal/

From a Linux machine we have here, I ran an openssl command (see attached code) to get the cert. I was able to copy the cert (starts with ----BEGIN CERTIFICATE----) and save it to my desktop as a .cer file. From there, I double-clicked on it to see all the details of the certificate including the expiration date.
openssl s_client -connect exchange_server.example.com:995 -showcerts
