Exchange Server Device Lock Time

[davidbrownds]

My Corp Email Exchange server is setup to force the Lock to be set to Simple Pin and 5 minutes. I would like to change this to something greater than 5 minutes, our Exchange admin wont change the setting on the server. I have looked everywhere on the device and in the registry on where the time for the Lock is stored. I can't find it. Dose anyone know where this might be and if it is possible to change the setting. It must be in the registry somewhere. If I delete the exchange server info form Active Sync the lock is still on and can't be changed either. Any help is much appreciated.

Thanks
Dave
