Using SSL certificates
If you have an SSL certificate installed on your control panel server, and you are using the Hosted Exchange 2003 service, you need to change the SSL settings on the control panel server to ensure that the Exchange Server Health Monitor (ESHM) functions correctly.
ESHM is an application that enables organization users to monitor the status of the Exchange server that hosts their mailboxes and to verify their Internet connection. If ESHM is enabled for user accounts, users can download and install it on their computers. After the application is installed, it shows the status of both the Exchange server and the Internet connection.
If the control panel server settings are incorrect, ESHM shows the Exchange server's status as gray, and recommends that users contact their service provider for assistance.
To change the SSL settings:
Log on to the control panel server as domain administrator.
Run the Internet Service Manager program:
Click Start, point to Programs, point to Administrative Tools, then click Internet Service Manager.
Find the ESHM virtual directory under Default Web Site.
Right-click ESHM, then click Properties.
Click the Directory Security tab.
Click Edit under the Secure Communications section.
Uncheck the box next to Require secure channel (SSL).
Click Apply.
