A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hi Benji,
Thank you for choosing to use OneNote.
Based on your description, you have concern that whether Microsoft can protect your company's confidentiality because OneNote for Win 10 just can store your notebooks on the cloud.
So my suggestion is to use OneNote 2016, you can download OneNote 2016 from this link. OneNote 2016 for Windows lets you create a new notebook to any folder including local folders or network shares. You can go to File>New>This PC.
The button named ‘Create in a different folder’ lets you choose any other folder (local or network) to create your notebooks, and you can choose a local place on your protected company server.
To save the notebook to the default OneDrive folder ( Documents/OneNote Notebooks ) type a Notebook Name and click ‘Create Notebook’.
Additionally, here is an article about the difference between OneNote (for Win 10)and OneNote 2016.
Thanks for your understanding and support for our products.
Regards,
Jazlyn
