A user asked: “Can you save a sent message on an individual basis to the sent folder or is it an all or nothing scenario?”
Yes, you can control it per message. Look on the Options ribbon in Outlook 2007 or
on the Options button/dialog in older versions. From this dialog you can choose a different folder to save the message, choose not save it or save it if your default is to not save sent messages.
