If you use Microsoft’s OneNote Class Notebook with your students and have encountered issues with the section permissions there is a simple fix for that. Mike Tholfsen (@mtholfsen) recently shared a link (see his Tweet here) that will allow you to quickly, and easily fix those permissions with the click of a button.
Simply head out to https://onenote.com/classnotebook/notebook-fix. Once you’re there and logged in with your Office 365 credentials, the site will load a list of Class Notebooks you have created or are the co-owner on. Simply press the purple “Fix Permissions” button and Microsoft will take care of the rest.
