How to remove the Outlook 2010 icon from tray?

How do I remove the Outlook 2010 icon from my Windows 7 system tray / notification area?

Just for clarification: i really mean 'remove' and not 'hide'.

I have the icon in the taskbar and I don't need to see a second redundant Outlook icon in my tray.

Right click taskbar and select properties. Under taskbar tab select "customize" then select which icons you want to show in system tray.

An alternative is to right-click the icon and select "Hide when minimized", that way you won't have two icons at the same time. I know that's not a perfect solution.

Another option is to remove the taskbar itself through a registry hack. See this Howtogeek article for more information.

I cannot find anything in the registry that allows me to disable the actual icon on its own.
