How to renew Exchange 2003 SSL Certificate

Issue: The certificate in use on your Exchange 2003 server has expired and needs to be renewed or replaced.

Background: Exchange 2003 running on Windows 2003 uses IIS 6.0, therefore the certificate is tied to the Default Website in IIS and can be renewed/replaced using IIS Manager.  SSL certificates are used to encrypt http sessions allowing you to run encrypted Outlook Web Access and Activesync sessions over port 443 (HTTPS).

In order to use a certificate that will be recognized by browsers and mobile devices you will need to purchase a certificate from a recognized third party certificate authority like GoDaddy, or checkout my guide on buying a cheap ssl certificate.

Steps:

Generate a certificate request (CSR):
open IIS Manager, expand Web Sites, right click Default Website, click properties.
properties of default website IIS

Click Directory Security > Server Certificates
