This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store.

I installed Certificate Server & configured it per

My intent is to issue SSL certificate for OWA and not get a "Certificate Error" in IE7.

When I access the web/OWA/Exchange server from a machine across the Internet, I receive the "Certificate Error".,  When I view the certificate, i find  "This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store."

I believe the certificate server was to resolve this.

Where to go from here?

    what you did is create a self signed certificate. Those are not automatically recognized by browsers. There are two ways to solve this:
    - Get a certificate from a trusted certificate issuer like Verisign, Thawte, Go Daddy, ... for your OWA server.
    - Import the public certificate from your issuing CA in the PCs which are accessing your OWA. This is only practical when they are under your control.
