It does do threading of a sort, apparently by the subject line (with RE:). Actually, NS Messenger will thread this way too, when no "References" header is available. Outlook98, as well as not providing "References", also ignores "References": I can send a reply from NS Messenger, which provides the Reference header, with a different subject line, and Outlook does not recognize it as belonging to the same thread (well, MS calls it "Conversation"). You could make an argument that threading by subject only is OK, since when subject lines are changed, that often means the writer is wanting to start a new thread; under Netscape, with no direct access to headers, he could not do it. Under Pine, etc., I guess you can.
It is certainly inexcusable for Outlook to ignore References, as well as not give any option for providing them. MS is the only company I know of that wants their stuff to not interoperate with others'. But NS should at least give you a "Terminate Thread" option on reply that would clear out the Reference headers.
