"The purpose of the Recycle Bin is not to provide another place where you can organize your data."
Love it. Like alegr1, the amount of computers (personal and corporate (when the recycle bin is not disabled)) I see that have gigabytes worth of data in the recycle bin and are actively being used (that is, when you ask them if they want it, they claim they do) is ridiculous.
As for messages in "Deleted items" in Outlook. Oh my goodness, don't go there.
