    Great tip, this change with Outlook 2010, I don’t know why they hid it in cleanup – thanks for the tip.

    I would like a button in the Quick Access toolbar as I need to clean out my various folders a couple of times each month when I exceed my allowed mail box size. This was right at the bottom of the Folder List in Outlook 2003, and it should be just as handy in 2010. It is my own bad habits that get me into this trouble, but I doubt that I will change anytime soon.
