"iCloud Settings-Out-of-Date" on Windows 10 mail app
I am having a wrestling match with the Windows 10 mail app and iCloud mail. The mail app simply won't connect. My mom needs her emails on the PC as well as her Mac. (Everything works fine on the Mac.) Now she's having to sign into iCloud every time she needs her emails on Windows, and this is annoying because it takes a long time. Any ideas or suggestions would be greatly received.
