A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Had the same issue and I just tried this method as:
- Enter into the One Note On-line page of the note you shared;
- Click the button "Share" on the right top;
- Select the "shared with" in the pop-up box and select "Advanced";
- Select the person that no longer to share with and click "Remove user permissions".
- You will find that the person deleted no longer found in the shared person list.
