I doubt that any mail client would include any old headers in reply e-mail, as replies are newly created messages. The headers belong to the old message; the new message has new headers appropriate for it. I'm pretty sure that Outlook discards all headers, even on forwards. Indeed, I'd never even realized that RFC-822 even defines reference headers (they're so rarely used; the Ada-France messages do have them, but that's the first time I've seen them in any mail - and I look at a lot of mail headers). I doubt that it would make sense to copy those headers in e-mail, unless the client knows what they are for (as in a newsreader). (How would you know if they apply to the reply? How do you know what to add to them? The contents of the reference header is not standardized for mail.) Randy.
