IMail Server and Web Messaging use the Microsoft Internet Information Services (IIS ) Secure Sockets Layer (SSL) features to encrypt communications between the IMail Web client and server.

You can set up the Web Calendaring server to use Secure Sockets Layer (SSL) for communications between a browser and the server .

To set up SSL for IMail Web Calendaring:

1. Use the IMail SSL Configuration Utility to set up the SSL certificate and public/private key pair. From the Start menu, select Programs > IMail Server > IMail SSL Configuration Utility.
2. In the IMail Administrator's Web Calendaring Server Settings page, click Enable SSL.
