The only way we know of is to reconnect to the BES and then edit the keystroke injection to allow.
John, your idea sounds like a runner but you would have to ensure that the policy on ExchangeMymail is set to allow or you would achieve nothing.
Incidentally, we have heard from some 8300 corporate users that they have been able to change the settings on the handheld even if the BES is set to the default deny. As such, maybe some of the newer OS versions work slightly differently? We haven't yet been able to establish which OS versions these people are running.
