- Product
- Microsoft OneNote
- Device & OS
- Mac
- Scenario
- OneNote closed unexpectedly on a MacBook, resulting in important notes disappearing from the application.
- Observed behavior
- Missing or deleted notes, pages, and sections within the OneNote notebook on the Mac after an unexpected app crash.
Ensure your Mac has an active and stable internet connection so you can reliably access OneDrive and OneNote Online for cloud-based recovery options.
Check Deleted Notes in OneNote Online
The fastest way to recover missing pages is to check the web version of OneNote, which maintains a recycle bin for deleted notes.
When notes disappear from the local Mac application, they might still be recoverable from the cloud recycle bin. OneNote Online stores deleted items for a limited time.
Open your preferred web browser, go to the official OneNote website, and sign in with your Microsoft account.
Locate and open the specific notebook where your notes went missing.
Click on the 'View' tab in the top ribbon and select 'Deleted Notes'.
Right-click on the missing page or section you want to recover, select 'Restore', and choose the destination section to move it back to your active notebook.
Use OneDrive Restore (Microsoft 365 Subscribers)
If your notebook is saved on OneDrive and you have an active Microsoft 365 subscription, you can roll back your entire OneDrive to a previous state.
Restore from Mac Time Machine Backup
If you regularly back up your Mac using Time Machine, you may be able to recover an earlier version of your locally cached OneNote files.
Experience Stable and Reliable Document Management with WPS Office
If you frequently experience unexpected crashes and lost data with Microsoft Office apps on your Mac, consider switching to WPS Office. It provides a lightweight, highly stable environment for all your document needs, while being completely compatible with standard Office formats.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button for Mac.
- 2. Install on Mac: Open the downloaded .dmg file and drag the WPS Office icon to your Applications folder.
- 3. Enable Cloud Backup: Sign in to your WPS account and enable cloud syncing to ensure your documents are safely backed up automatically as you work.

Frequently Asked Questions
How long do deleted notes stay in the OneNote recycle bin?
By default, OneNote retains deleted pages and sections in the 'Deleted Notes' section for 60 days. After this period, they are permanently erased and cannot be recovered through the recycle bin.
Why did my OneNote notes disappear after an app crash on my Mac?
Unexpected crashes can prevent OneNote from syncing your most recent, locally cached changes to the cloud. If the local cache file gets corrupted during the crash, those unsynced notes may disappear when you reopen the app.
Can I recover unsynced OneNote pages on Mac?
Unsynced pages are difficult to recover because they never made it to OneDrive. Your best option in this scenario is checking if a Mac Time Machine backup successfully captured the local OneNote cache files right before the application crashed.
What should I do if none of the standard recovery methods work?
If checking OneNote Online, OneDrive Restore, and Time Machine all fail, you can try contacting Microsoft OneDrive support for further assistance or consult a professional data-recovery service to see if the local cache can be salvaged.
