Using Classic Outlook on Windows for personal email, calendar, and contact management
So no one did apply the real fix for the issue? Wo kaorund are helpful, and there at least 10... This fixes it really..
Sooo... as I said, it was never removed, just some bug.
I have managed to fix it... I was debugging the app with Edge DevTools, and a .js file was missing...I deleted all application data... and now it's working like before !
However, I had to reconnect my account, so if you have MS accounts, that's not an issue, but for others I cannot say. Probably deinstalling and reinstalling the app would work too. Note that purginf from Dev Tools, it will not impact anything else (like your emails, settings, etc. wil not be affected), just
You can run the app like this: olk.exe --devtools from the terminal, or from Win+R (run).
The dev tools will open with the app:
Got to application -> Storage -> Clear Site Data.
You can try to remove only the cache and the indexed DB (edit: tested it since it's enough to fix it) first, but I think you'll have to reconnect to your account anyway.
Restart the App!
After that:
