By default, Outlook saves copies of calendar items, contacts, and tasks that are opened and have not been saved by the user, in addition to autosaving unsent e-mail messages. Items are autosaved to the user's Drafts folder. You can disable this feature so that Outlook autosaves only unsent e-mail messages.
