Hi hendrika290,
Thank you for using Apple Support Communities.
It appears that you have an issue with setting up iCloud email to your PC. You have reviewed the Two-factor authentication for Apple ID resource. We want to help. To make sure that we are covering everything about setting it up, you can follow the steps in this article that explains how to Set up iCloud Mail on your device. You want to look under the "Set up a Windows computer with Microsoft Outlook"
If you still have an issue, is your Apple ID updated with all payment information, etc?
Best Regards!
