Threaded mail readers like pipermail use 'References:' or 'In-Reply-To:'
headers in the email to figure out the threads, not 'Subject:'.

AFAIK outlook *does* create 'References:' headers even if it doesn't use
them. Probably your user's mailserver is stripping them out before they
get anywhere near mailman - ms exchange is your likely culprit here.
