Using New Outlook on Windows for personal email, calendar, and contact management

This was driving me crazy, too... and like you, un-selecting text predictions in mail settings did NOT work... however, I FINALLY figured out that if you go to Editor (in Outlook: easiest to find on the right side of the tool bar if you start a new message) and select "editor settings" there is ANOTHER auto-fill option there. I un-selected that auto-fill and it seems to actually (finally be off!). I can think and write! I hope this works for others.
