All messages in my Drafts folder (almost all) dating prior to September 2007 are now marked (UNKNOWN) and their contents has become a message I never sent to someone in 2007. Many of these messages were actually sent and I just opted to use the Drafts folder to archive them. What has happened to these messages? If this is a policy thing, why didn't I get any notification of it; I had some extremely important messages in there!!!!!!
