OneNote Web Clipper does not work with OneDrive for Business

Hi Jens-Volker 

Thank you for posting the question on our forum. I am sorry that you're not able to save your Web Clips to OneNote notebooks linked to OneDrive for Business account. According to your description, the issue seems to be due to a limit on the number of OneNote items in OneDrive library for a given OneDrive account.
