Using Classic Outlook on Windows for personal email, calendar, and contact management
Thanks for the hint Damien,
I found the same, but 3 languages are not enough, and unfortunately it seems not to work anyway. For me it always is stuck on the language I (prioritize) move to the top of the list. If English is on top and I write German, then all German words get marked as wrong, and vice versa. Moving the Language that I'm currently writing to the top, solves the issue. But as soon as I write in an other language, I have to dig into the editor menu again.
Seems like US organizations developing software are regularly forgetting, that outside the US there are actually people capable of communicating in more than one language.... 😏 It's not just Microsoft
