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? -- George
