How to make Icloud mail work on windows 11

Would I have to generate one for each computer using Windows 10/11 or can I use the same password. Each time that I generate an app-specific password it says that it is "out of date".

I also have iCloud for Windows installed but that doesn't seem to help the issue of connecting and syncing.

You need to generate and use an AppSpecific password.

App-specific passwords

Have you gotten it to work with app specific passwords?

I turned on 2FA and generated an app-specific password for Windows Mail but this didn't work. Any other suggestions?
