All I can say is there are reasons why these policies are forced onto any domain resources (yes that include your TP2): Security & Safety.

See if you can talk with your Exchange Administrator and have him change some policies that are by default, limited on mobile devices.

As for registry hacks, eventually Microsoft finds them out and patches them in newer releases. After all Microsoft doesn't do Windows Update on WM devices like they do with the desktop OSes.

I'd have a little talk with the Exchange Admin if I was you.
