It worked flawlessly for years till today. Now I'm getting error message 'Server does not support ActiveSync 2.5 or 14.0 (only 16.1). TbSync will not work with this ActiveSync server. Please fix it if possible!

I'm using Thunderbird 148. But this problem was showing before I finally upgraded from a much older version (I think it was 115 or so, and I used TbSync 4.7 for a long time on it without problems).
