Although you can sign up for multiple One DRIVE accounts, only one can be ASSOCIATED with OneNote. To open a notebook from another account (WHETHER it’s another one of your own or someone else’s account), MAKE sure it’s shared with your primary One Drive account. As soon as it’s been shared, you should see the notebook listed under Files shared with you in your primary One Drive account. Right-click or tap and HOLD on the notebook and select Open in OneNote from the context menu to open the notebook in OneNote.
