Request Edge Certificates

Lync Server 2010

Topic Last Modified: 2010-11-07

The certificates required to support external user access include certificates issued by a public certification authority (CA), and certificates issued by an internal Enterprise CA:

  • Certificates required for the external interface of Edge Servers and the reverse proxy must be issued by a public CA.

  • Certificates required for the internal interface can be issued by either a public CA or an internal enterprise CA. We recommend using an internal Windows Server 2008 CA or Windows Server 2008 R2 CA for creating these certificates to save on the expense of using public certificates.

It can take time to process certificate requests, especially requests to public CAs, so you should request certificates for your Edge Servers early enough to ensure that they are available when you start deployment of your Edge Server components. For a summary of certificate requirements for Edge Servers, see Certificate Requirements for External User Access.
