Fix 'Not the Owner' Error for OneNote Notebooks in SharePoint
Question details
The user is unable to manage permissions or sharing settings for a OneNote notebook they created and uploaded to a SharePoint document library.

- Product
- Microsoft OneNote / SharePoint
- Device & OS
- not provided
- Scenario
- Trying to change sharing or access settings for a OneNote notebook stored in a SharePoint document library.
- Observed behavior
- The system shows an error stating the user is not the owner, preventing them from modifying the notebook's permissions despite having Edit access.
Confirm whether you have "Edit" or "Full Control" access to the SharePoint document library where the notebook is stored, as this directly determines your ability to manage file permissions.
Request Full Control Permission from the SharePoint Owner
Since SharePoint document libraries inherit site permissions, you must have Full Control access to change who can access the notebook.
When a OneNote notebook is saved to a SharePoint document library, it stops functioning like a standalone personal file. Instead, it becomes a SharePoint library item. Even if you originally created the notebook, its sharing and access rules are now governed entirely by the SharePoint site or library settings.
Standard 'Edit' permissions allow you to modify the notebook's contents, but only users with 'Full Control' can change its permission settings.
Find out who manages or administrates the SharePoint site where your document library is hosted.
Contact the administrator and request "Full Control" access for your user account, either for the entire document library or specifically for the notebook item.
Once the administrator grants Full Control, open the SharePoint document library in your web browser.
Right-click the OneNote notebook, select "Manage Access" or "Share", and you will now be authorized to modify the permissions and invite new users.

Frequently Asked Questions
Why can I edit the OneNote notebook but not share it?
Having "Edit" permission in a SharePoint library allows you to add or modify the contents of the notebook. However, modifying sharing settings or changing who has access requires "Full Control" permission, which is typically restricted to site or library owners.
Does moving a OneNote notebook to SharePoint change its ownership?
Yes. Once uploaded or saved to a SharePoint document library, the notebook inherits the library's permission structure. Individual ownership is replaced by the centralized access rules of the SharePoint site.
How can I keep full control of my OneNote notebook while sharing it?
If you want to retain sole ownership and easily manage permissions yourself, save the notebook to your personal OneDrive instead of a shared SharePoint library. From OneDrive, you can directly control who has view or edit access without needing SharePoint administrator rights.
