Force Outlook to use cached or online mode

You can force Outlook on a single computer to use cached or online mode without creating a group policy by setting this registry value:

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Cached Mode

Where xx.0 is 14.0 for Outlook 2010 and 15.0 for Outlook 2013. Set this value to 1 to force cached mode or 0 to force online mode.
