Policy
Allow a shared Books folder
This policy setting lets you decide whether Microsoft Edge stores books from the Books tab to a default, shared folder for Windows. If you enable this setting, Microsoft Edge automatically downloads book files to a common, shared folder and prevents students and teachers from removing the book from the Books tab. For this to work properly, your students and teachers must be signed in using a school account. If you disable or don't configure this setting, Microsoft Edge downloads book files to a per-user folder for each student or teacher.
