    You should obtain a UC (Unified communications) certificate from a SSL certificate vendor.

    They will provide you with instructions on how to import using the Exchange management shell (Import-ExchangeCertificate and then Enable-ExchangeCertificate).

    In order for autodiscover to work properly you will need to include and the local fully qualified and netbios names such as server.domain.local and just 'server'.

          It isn't a "free" certificate.
          It is a self signed certificate that is used as a place holder for a commercial signed certificate. Microsoft do not support the self signed certificate with Outlook Anywhere or Exchange ActiveSync.

          Given the headaches with managing a self signed certificate, plus the security risk, it isn't worth pursuing it simply to save $80 for a commercial SAN/UC certificate.

          I have instructions on changing to a commercial certificate here:
