I have a 2010 exchange server that is acting as a mail server. All of our users are getting certificate errors. We are looking to purchase a SANS UCC certificate and would like any suggestions on a good place to buy one. Also want it to be as easy possible, to just install it and have it work.
Would we need an SSL certificate if users are accessing the site via the web.? https://mail.domain.com/owa
Example of what I was thinking to have on the cert.
