I am trying to get exchange activesync set up with my Cingular AT&T phone. I get the error The security certificate on the server is invalid. Contact your exchange server administrator or ISP to install a valid certificate on the server.

Now our work does have an ssl as we are using outlook web access.

I have found an article on Microsofts site but it says to contact my provider.

Any idea's? Is the cert bad? Do you need one specifically for WM5?

TIA,
Brett
