I have an application server that runs a Helpdesk software called Numara TrackIt 8.5. When it tries to send out email notifications via SMTP to our Exchange 2007 server, it gives a SSL certificate invalid errors. Our SSL certificates for the Exchange 2007 server are through DigiCert and are still valid. I have confirmed that the problem isn't with TrackIt, rather than either an improperly imported SSL certificate on our application server or Exchange configuration error.
Could someone provide me with steps that would allow me to successfully export the public SSL key (which is what I believe it needs in order to connect to the SMTP service on Exchange via SSL) from the Exchange Server and correctly import it into my application server? Both servers run Windows Server 2003 Standard.
