I have created a CSR for our Microsoft Exchange 2010 Server (domain: mail.domain.com (example). We have a hosting account with Godady (DNS Hosting only as well). We do not have SSL Cert and need to purchase one. However, which SSL to purchase? https://www.godaddy.com/ssl/ssl-certificates.aspx?ci=9039

We only need a SSL cert for mail.domain.com (https://mail.domain.com) Would the "Protect one website option work?) Godaddy is suggesting we use the multiple domain or even wild card package. However due to only needed a cert for one subdomain/domain (https://mail.domain.com) this is why I this the basic options would be our best option. Do you agree?

    Purchase a not-GoDaddy-SSL-cert, for starters ... go with someone good. Jan 7, 2015 at 20:28
  • That does not help. Say I go with someone else? Who? Should I get a SSL Cert for subdomains? Wildcard? Jan 7, 2015 at 20:32
  • www. certificatesforexchange. com is what I always use and recommend. Simple, easy, done. (not a plug for them just a recommendation, so I've messed with the URL a little). You'll need multiple SANs for Autodiscover, external, internal, netbios name even.

  • @TheCleaner Internal and netbios names are no longer available. digicert.com/internal-names.htm

  • Correct, I'm just rambling from years of it. It's best to use proper FQDNs on the internal Exchange URLs.

You should get the UCC SAN certificate as GoDaddy suggests. You need AT LEAST two FQDNs - autodiscover.domain.com and mail.domain.com.

Never had an issue with Godaddy certs.
