About Outlook Exchange Proxy Server: Why can’t I connect?

Exchange server:

Outlook Exchange Server uses the Mailbox server role (multi-role server) to send outbound emails through Send connectors. Send connectors allow you  to send email from your Exchange server to other domains on the Internet. When you click on the properties of Exchange’s Send connector, you’ll find an option to proxy through a Client Access server.

A proxy server is a network from which all your client queries or requests will be sent to the main server.

The error: Outlook cannot connect to the proxy server has something to do with the security certificate of the proxy server.
