    Hi,

    First of all, I’m total noob for Exchange services. I have deployed Exchange 2013 in my lab to test one software integration via EWS. All the time, I have “Invalid credentials (401)” error, and I could not troubleshoot in detail. So I downloaded EWSEditor to test connection to my local Exchange server. After testing Exchange services configuration, I’m getting following:

    Message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
    Exception details:
    Message: The remote certificate is invalid according to the validation procedure.

    Now, since I don’t have enough skill with Exchange nor CA, what do I need to setup (regarding certificates) on client side so EWS connection would work properly?
