Utility Room

On OS X, Microsoft Office creates its very own folder, called "Microsoft User Data", in your Documents folder. To get rid of it, try moving it to ~/Library/Preferences/. That worked for me.

This had been annoying me for years. Solution was found from macosxhints.com.. well, actually one comment linked to macnn.com which had the working solution. (Another comment in macosxhints.com suggested moving the MS User Data Folder to ~/Library/, but that didn't do the trick.
