What kind of SSL certificate do I need for Exchange 2013?

  • 772

We're running a single domain on a single Exchange 2013 server. I'm currently trying to determine what kind of SSL cert I need.

Right now I'm unsure why I need a UC (Unified Communications) Certificate like this one.

I can understand why something like this wildcard certificate would be necessary.

Any direction would be helpful!

    A UC certificate is perfectly fine. The only names you really need are the external URL you will use for OWA/Outlook Anywhere (such as mail.mycompany.com) and autodiscover.mycompany.com. If you plan on using TLS for encrypted mail transport, you will need to include the FQDN that you use on your send connector, which also could just be mail.mycompany.com.

    I would recommend a wildcard certificate if you want to use one certificate for a ton of other web applications under the same domain name. You will have to set your Outlook Provider appropriately if you use a wildcard cert:

    Set-OutlookProvider EXPR -CertPrincipalName 'msstd:*.mycompany.com'
