You can check your editing history on OneNote Online by clicking on the View tab and then on Page Versions. This will show you previously saved versions of your notebook.
To go more in-depth into the editing history, you will need to open OneNote on your desktop. Next, select the History tab, which will give you access to Recent Edits and previous Page Versions, which you can filter by author and the dates things were edited.
