A Secure Sockets Layer (SSL) certificate is required on all computers that use the 2007 R2 version of Communicator Web Access client for desktop sharing. The SSL certificate must be issued by a trusted certification authority (CA). Alternatively, the certificate can be issued by a company that is chained to a CA that the computer trusts. If you are using certificates from a public CA, an SSL certificate from the CA may already be installed in the Trusted Root Certification Authorities certificate store on client computers.
