    Hi,

    I’m sorry to hear you’ve lost your OneNote notes.

    To better understand what happened, could you let me know:

    • Was this a notebook stored in OneDrive/ SharePoint (Microsoft 365 for Business) or a local notebook on your PC?
    • Which version of OneNote are you using (OneNote for Windows, OneNote desktop, or OneNote on the web)?
    • Did the entire notebook disappear, or are only certain sections or pages missing?

    In the meantime, you can try the following:

    • Check whether the notebook is still available in OneDrive or SharePoint and confirm you’re signed in with the correct work account.
    • In OneNote, go to History > Notebook Recycle Bin (if available) to see whether the missing pages or sections can be restored.
    • If the notebook is stored in OneDrive, also check the OneDrive Recycle Bin for deleted notebook files.

    You can find Microsoft’s guidance here:

    I look forward to your update.
