iCloud Notes Sync Problem in Outlook 2016 on a Windows Computer

Dear Apple Customer Service,

I am trying to set up my Microsoft Outlook 2016 so I can view the iCloud notes created on my iPhone. I have tried everything suggested both on Apple and Microsoft Forums available to that topic dating back as far as 2015. Calenders, Tasks and Contacts are synced - still the Notes are not showing up anywhere. As I don't want to open the Webversion of iCloud continously I do hope for a solution provided by you, the Customer Service.

I run Windows 8.1.

I run iOs 12.5.4 on my iPhone 5s.

iCloud is up-to-date.

Outlook is up-to-date.

iCloud Add-In for Outlook is working fine.

Forum entries I have tried (selection):

Notes not synchronised between iCloud & MS Outlook

iCloud notes is not syncing with Microsoft outlook

https://discussions.apple.com/thread/7937251

Might it be that iCloud Notes have stopped working together with Microsoft Outlook with a certain iOs-Update? So only Calender, Contacts and Tasks can be synchronized with the iCloud Add-in (see below)?

But then how to import notes anyway? I tried setting it up over my Icloud-Email-Account (...@icloud.com / ....@me.com) but the Notes-Folder remains empty. (see below)

It could be that I accidently deleted the Notes folder in the iCloud-Hierarchy a while ago - if I try to create a folder called "Notes" an Error Messages shows (see below) - still the folder doesnt show up. (Any other folder can't be created either but for missing permission rights). Is there any way to get that folder back and in such a way maybe restore the Notes?

Best Regards,

Daniel
