How to Configure SSL for HTTP
You can configure an Exchange HTTP virtual server to use SSL.
To configure SSL for HTTP
In Internet Services Manager, for the default Exchange HTTP virtual server, right-click Default Web Site, and then click Properties.
Click the Directory Security tab, and then select Server Certificate.
Follow the instructions in the wizard, using the Internet Information Services 6.0 Product Documentation as a reference, to request and install the SSL certificate. HTTP SSL is configured individually for each virtual server or Web site, so if you create additional HTTP virtual servers in Exchange System Manager, you must configure SSL for each server or Web site as it is referred to in Internet Services Manager.
