I don't have threading in my mail client I would be surprised if Outlook didn't have threading (on the other hand.. it's Outlock ;-) you just might not be aware of it. Are the mails you see on the list really not grouped by topics and you don't see who answers whom respectively which mail? > I am told that touching the subject will break threading, That was an assumption because it happened with a mail where you changed the subject. It may be completely unrelated. Seeing now that breaking threads is the usual way your mails arrived it probably is. > What may have happened is I replied to my own copy rather than the one > from the list. That might indeed be a cause as then maybe Outlook doesn't relate the copy to the mail on the list. Strange though because the original mail even when copied has the necessary information in its Message-Id to generate an In-Reply-To from, so it's just Outlook's way of treating things badly. I dug a bit through the mails where you did not break the thread, they all have a header (presumably generated by Outlook) of the form Thread-Index: AQBpnn24FNQrQXs8MaBDRnME+JC2HgFk3Q0il/lp8SA= Note the / slash. All mails that break the thread also have a Thread-Index header, but noticeably shorter and without a / slash part. I guess the /part is some index into the thread and you replied the breakers from the inbox and not the list folder. > I usually delete my own copy as soon as one from the > list appears, and that might matter.
