I don't think that's correct.  

I've yet to find anything authoritative (and non-ambiguous) on the
subject, but my understanding is that either or both of the Thread-Topic
and Thread-Index fields are used, Thread-Index being generated from
References.  

Then again, I doubt all versions of Outlook generate identical headers,
or behave consistently with respect to threading.

Anyone have more information?
