I've ran through the tests at http://testexchangeconnectivity.com/ and The ActiveSync test is passing, but with warnings.
This is the warning I get:
Only able to build certificate chain when using the
Root Certificate Update functionality
from Windows Update. Your server may
not be properly configured to send
down the required intermediate
certificates to complete the chain.
Consult the certificate installation
instructions or FAQ's from your
Certificate Authority for more
information.
I purchased the SSL cert from godaddy, but I'm not quite sure where to go from here.

Use http://www.sslshopper.com/ssl-checker.html to see what Intermediate certificates are being given out by the server. It should be giving out everything except for the last root certificate. You can see what the chain should be by viewing the certificate in a web browser. If it is missing any Intermediates, just find the Intermediates bundle file that GoDaddy sent you and install it on the server.
