Based on the described symptoms, the notes are no longer present in the OneNote notebooks stored in the cloud (they do not appear in OneNote for the web or in the recycle bin), and OneNote on Android reports that the pages have been moved or deleted. In this situation, only the following recovery paths are available:
- Check if the notes are in another notebook or section
- On any OneNote client that can still open the notebook structure (Windows, web, or Android), search across all notebooks for unique words from those notes (for example, a specific term or phrase used only in that content).
- If the content was accidentally moved to another page or section, search can locate it.
- Check OneDrive/SharePoint directly for notebook versions
- Sign in to OneDrive from the OneDrive home page.
- Browse folders such as Documents or Notebooks and locate the affected notebook.
- Open the notebook in OneNote for the web.
- If the service where the notebook is stored supports version history, restore an earlier version of the affected section or page from there (if available).
- Check OneNote recycle locations
- If using the Windows OneNote app with shared notebooks:
- Open the notebook where the notes used to be.
- Select History > Notebook Recycle Bin > Notebook Recycle Bin.
- If the missing pages appear there, right‑click each page tab, choose Move or Copy, and move them back to a normal section.
- If using OneNote for Windows 10:
- Open the notebook.
- Select View > Deleted Notes.
- If the pages appear, restore them using Restore To.
- Check for local/backup copies (if any)
- If the notebook was ever opened in the desktop OneNote app (not just Android), and local backups were enabled, earlier backups of sections or pages might exist and can be restored from that machine.
If the notebook has fully synced after the deletion/move event and none of the above locations (OneNote for the web, OneDrive folders, Notebook Recycle Bin/Deleted Notes, or local backups) contain the missing content, recovery is very limited. OneNote does not maintain a separate “trash” for individual content containers on a page, and if no backup or older version exists, the data cannot be restored.
For future protection, enable and regularly check backups in the desktop OneNote app (if used) and periodically export or copy critical notes to additional locations.
