For a deleted OneNote page or section, start with the notebook’s own deleted-note area. For a whole missing cloud notebook, check the service where it was stored. A desktop backup is another source, while a local cache is not automatically a portable notebook backup. First identify the client, account and storage location.

Recover a page in OneNote desktop for Windows
These steps concern OneNote for Microsoft 365/2024/2021 desktop on Windows, rather than assuming the retired OneNote for Windows 10 client has identical menus.
- Open the notebook where the page belonged and choose History > Notebook Recycle Bin.
- Locate the page or section. Right-click it and choose Move or Copy.
- Select a suitable destination section and move/copy the recovered content there.
- Open the restored page and inspect its actual text and attachments.
Microsoft documents recovery up to 60 days after deletion unless the notebook recycle bin was emptied or applicable conditions prevent access. Do not treat that period as an assurance that a particular page remains. See Recover deleted notes. The web interface can use View > Deleted Notes instead.
Use an existing desktop backup
In the Windows desktop app, select File > Info > Open Backups. Open a dated notebook/section backup, inspect its contents, then use the section/page’s Move or Copy route to place needed content into a working notebook. Close the backup section when done to avoid editing the wrong source.
This requires a backup containing the relevant content. Retention and available backup controls vary by client; Microsoft’s platform recovery comparison distinguishes supported routes. Enabling backups now cannot recreate missing old pages.
A whole notebook is missing
Verify the correct personal, work or school account and the notebook’s hosting service. Check OneDrive or the relevant SharePoint site’s recycle bin for a notebook deleted at the file/service level. Service retention is separate from the OneNote page recycle bin and may be governed by the organization.
If a notebook remains visible on another device but contains unsynchronized work, preserve that content before resetting the app, clearing cache or replacing its local data. A sync error can make one client look empty without proving every copy is gone.
Treat local data as an application-specific recovery source
An available local cache or section file should be preserved with its context. Do not replace cache folders from another installation or assume that a found filename can be opened as a complete notebook. XRecovery can search readable storage for remaining files; you can then check the recovered content through OneNote’s own backup or recovery workflow. A cache filename alone does not establish that a complete notebook can be restored.
Verify restored page hierarchy, text, images, ink and required attachments. Open attachments from a working copy and confirm their content. Then check synchronization under the intended account. A recovered page title without its body or embedded material has not completed the task.
