how to keep Exchange server sync secure?

[mlevin77]

I use over-the-air wireless sync (Activesync) to get email from an Exchange server. If the phone is ever lost or stolen, is there an easy way to disable this remotely? I don't want to have to enter my password every time I check email (dozens per day), but if something happens, I don't want anyone to be able to mess with my Exchange account info through this phone. Any good solutions to disable this remotely?
