If people have lost access to the Content Library in a Staff Notebook or Class Notebook you’re the owner of, visit the fix OneNote page. Select Fix Permissions beside the notebook people are having trouble with. When you see Permissions Fixed, they should have access again.
To help avoid this problem in the future, we recommend installing an update to your app.
Why this happens: Content Library has special read-only permissions. When the permissions get interrupted (like when a read-only section group is moved) Class and Staff Notebooks automatically restrict access to the Content Library so that only the owner can see it.
When this happens, everything is still in your Content Library. While it’s locked down, staff members and students can’t see it.
