Security is an important aspect of any Exchange 2010 installation. By default, all Exchange 2010 protocols, including Outlook Web App, Exchange ActiveSync, and the Autodiscover Service are automatically configured for Secure Sockets Layer (SSL) connectivity. For more information about Exchange Client Access and SSL see Understanding Digital Certificates and SSL.
It is not supported to locate an Exchange 2010 Client Access server in a perimeter network. Exchange 2010 Client Access servers have direct access to Exchange 2010 Mailbox servers.
