Untrusted certificates

I was not sure what section to post this, but I figure since it sort of revolves around security, this might be the right place for it. Has anyone run into any issues trying to use untrusted certificates in windows 7? I am not sure if windows 7 handles those differently than xp, I have an exhange server that is using a self signed cert, and when I can't seem to get outlook to work with the certificate. The xp machines work fine. I installed the cert, but still no luck, it is installed the trusted root cert folder. Is there something different I need to do to make this work?

Solved the issue, unlike xp, seems you have to make sure to install the certificate to the trusted root.
