Comments on How to add CalDAV and CardDAV accounts and sync with Windows 10
It used to work, I just reinstalled windows and I'm unable to add a dummy Icloud account. Windows says that they can't check the credentials as expected, but the account is no more added to the list and can't be edited. Tried any of this in the latest windows version?
The issue I spoke of seems to have been fixed in latest windows build (Version 10.0.19044 Build 19044)
