Yeah. Outlook does APPEND+EXPUNGE instead of MOVE.
That rather critical item should probably be mentioned in the configuration manual; in my searching about on the problem, I didn't find anything that indicated this Microsoft-caused limitation. On the upside, I'm glad I found it in my testing since I often use Roundcube and Thunderbird, which (now that I've looked) seem to do it correctly.
Besides, I can't think of a safe way to reliably detect that other than declaring moves to any folder other than spam to be ham. Guess I continue having Outlook users copy false positives from the spam folder into a separate reporting folder for cron to pick up.
Thanks!
