icloud sync - "unauthorized"

If I use iCloud for my calender (or anything else) it respons: Server notes (or in German: “meldet”) “unauthorized”?

I use Win 10 64Bit and the latest EMClient.

What did I do wrong? It is the correct password and the correct Apple ID.

I don’t want to use outlook anymore. And with Thunderbird iCloud-sync is not possible.

May anyone help me and the know the issue?

Best regards

Hi, thank you.

Meanwhile I found the problem: It was the two-factor authorization. When I deactivated it, it worked till now very well.

But nevertheless thank you.
