Why couldn´t my Outlook configuration be started because of an unknown failure?

Hello!

Today I uninstalled and after a reboot reinstalled iCloud 4.1 for windows on my Windows 10 PC. On the one hand I had read that iCloud doesn´t still work with Win 10, on the other hand I also read that it would work after uninstalling and reinstalling iCloud.

But now I have another problem: After I had installed iCloud again and had logged in to my account, I was asked to configure my calendar, contacts and tasks. When I did so, suddenly the configuration stopped with the notice: "Your configuration could not be started because of an unknown failure."

I tried it several times, even deactivated my antivirus software, nothing helped. What can I do?

Thanks for every help!
