OK, we have "set sort=threads", as the above implies some threads showing. > I tried setting strict_threads but it doesn't help. That just reduces threading, by disabling pseudo-threading. Having $strict_threads and $sort_re unset should compensate for missing threading headers, perhaps too much, if a subject recurs in later threads. > EG I have a thread with a friend (he uses the email app in Win10 and > the messages have outlook.com IDs) and checked all his Message-ID and > all my In-Reply-To and they look like they should match properly. > Each message contains the correct ID and Reference AFAICS. > > Any ideas what to try to solve this? What happens to the headers when you use & to join a tagged mail to a thread? Presumably the thread display is now OK, and the change in the headers will show whether it's In-Reply-To or a Reference that was missing. (Whenever I've done that, mutt has added an In-Reply-To, IIRC.) Erik
