Jon was having issues with not being able to edit pages in our team’s OneNote notebook. He reminded me that we dealt with something similar when he first started working here and that I was able to fix that issue pretty quickly, but something must have changed since then because those pages are a subset of the larger notebook that we’re now having issues with.
We believe we have a working solution: SharePoint > Site Contents > Site Assets > Options > Share > Who would you like this link to work for? Specific People > Apply > [add email address] > Send.
This appeared to work for his laptop and iPad when accessing OneNote using the web interface, not the native apps. Hopefully this is the solution we’re looking for. We’ll know in our upcoming Weekly Office Meeting.
I tried a slightly different approach that worked temporarily, but didn’t lead to a permanent fix: SharePoint > Site Contents > Site Assets > Options > Manage access > adjust permissions to “Can edit.”
