    Hi Support,

    I have encountered 1 error message in communicator 2007 R2 version.

    "There is a problem with the proxy server's security certificate.
    The security certificate is not from a trusted certifying authority.

    Outlook is unable to connect to the proxy server (Error Code ."

    Pls kindly check and advice the above error message.

    Thanks. Victor

    Is this all clients or only some?
    What sort of certificate are you using?
    Is Outlook on a domain member?
    Have you imported any relevant certificates on the client?

      you have created a self-signed certificate.

      two options.

      1) buy a proper SSL certificate.
      2) ensure that all your clients trust your root authority.
