If you plan on sharing a OneNote 2016 notebook—with yourself or others—it's best to create it on OneDrive right from the start. However, you can move a notebook to OneDrive after you’ve created it on your computer.
Note: If your organization uses SharePoint, you can share a OneNote 2016 notebook on SharePoint instead of on OneDrive.
In OneNote, open the notebook that you want to share on OneDrive.
Choose File > Share.
Select a location for your notebook, or choose Add a Place and then sign into your OneDrive account. If you don’t already have one, you can sign up for free.
Enter a name for your notebook (if you like, you can keep the name it already has), and then choose Move Notebook.
After you see the location in the list, select it.
OneNote moves the notebook from your computer to OneDrive, and confirms the move with the message: “Your notebook is now syncing to the new location.”
Tip: You can share a notebook with others using the Invite People button. This will let you send the people you select an email message with a link to your shared notebook. Depending on the permissions you’ve set for them on OneDrive, they’ll be able to either view or also modify your notes there.
