Using Autodiscover with a self signed certificate on Windows Mobile Devices

This KBA explains how to install a self signed certificate on the Windows Mobile device. The Windows Mobile device doesn't allow you to accept all certificates like other devices do when configuring ActiveSync. Follow this KBA if you're using a self signed certificate with AutoDiscover and a Windows Mobile Device.

Note: It is required to create an alternate host name for the self signed certificate called autodiscover.domain.com. If you haven't done this on an existing certificate, it is required you create a new one..
