Export / Import the certificate from exchange server including the private key to the TMG server and create a publish OWA rule from TMG server.

forget the default exchange certificate, I can't say this enough using it will ALWAYS lead to troubles sooner or later.

You really want to have to go back and edit all users once the self-signed certificate expires? no i don't think so!

Just do it right from the start pay $60/year and get a certificate and get done with it once and for all
It would be better to invest in a certificate rather than use a self-signed certificate. A self-signed certificate will always prompt a web security dialog unless you plan to install the ROOT certificate in each client so that the SSL can be trusted.

Anyway, in order to proceed with the setup, generate a CSR request and submit it to a certifying authority - 3rd party or your internal certificate server. Once you have the certificate, import it in to the Exchange server instance on IIS. Also, export the certificate with the Key as the same needs to be imported in to TMG.
