I consider this a bug, since even if the settings were enforced by Exchange, the setting should be removed after removing from control panel. So basically it is ignoring any setting in personalization, and is fixed at 1 minute with screen lock. Locks the screen, even though this is not set either. But if I change the screensaver timeout value, as soon as I go back into the settings, it is back at 1 minute.Īctually I managed to get it to say 15 minutes in there by editing the local GPO (User Config\Admin Templates\Personalization\Screen saver timeout) but even when it says 15 minutes in there, it comes on after 1 minute. I got so fed up with it I removed the Exchange account from mail app and rebooted. I believe it was change by the mail app, enforcing Exchange ActiveSync policies to 1 minute (even though the server does not enforce 1 minute on a phone).
I am unable to change the screensaver timeout in Windows 8 Pro RTM.
