OutlookShutdownWarning on Outlook 2010?

I'm trying to suppress the “Are you sure you want to quit Outlook?” message. I set the OutlookShutdownWarning registry key to false, but nothing happens. The document seems to indicate this relates to Outlook 2003.
How do I achieve the same thing in Outlook 2010...?

I've just tried this and it is working for me. Here are the contents of my .reg file to disbale the prompt. I'm running the latest version of MatterCentre but I'm not aware of any changes in that area.
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\FWBS\OMS\2.0] “OutlookShutdownWarning”=“False”

We had it in:
HKEY_CURRENT_USER\Software\Policies\FWBS\oms\2.0\Debug\OutlookShutdownWarning If I take it up a level, ie out of the “Debug” folder, it works!
I'm pretty sure this was working in its current location for 2003, but not to worry, the important thing is it's gone now!
