Question details
The user is experiencing a recurring issue where Microsoft OneNote crashes and fails to open correctly due to an application error.

- Product
- Microsoft OneNote
- Device & OS
- Windows
- Scenario
- Attempting to open or use Microsoft OneNote for daily note-taking tasks.
- Observed behavior
- OneNote unexpectedly closes and displays an error indicating it has encountered a problem and must be closed, likely due to corrupted files, outdated software, or damaged local notebooks.
Before attempting any repairs, try to manually back up any local, unsynced notebooks to an external drive or cloud storage to prevent data loss.
Update and Repair the OneNote Application
Running Microsoft Office's built-in update and repair tools can safely fix most application crashes caused by outdated or corrupted installation files.
Microsoft Windows includes built-in repair tools specifically designed to fix Office applications without deleting your personal files. A Quick Repair fixes most missing or corrupted files, while an Online Repair performs a comprehensive reinstallation.
Open OneNote (if possible), navigate to File > Account, select Update Options, and click Update Now to ensure you are on the latest version.
Press the Windows key + I to open your Windows Settings, then navigate to Apps > Installed apps (or Apps & features on older Windows versions).
Scroll down the list to locate Microsoft OneNote or Microsoft 365. Click the three dots next to it (or select it directly) and choose Advanced options.
Scroll down to the Reset section and click on Quick Repair. Wait for the process to finish and test OneNote again.
If Quick Repair does not resolve the crashing issue, return to the Advanced options menu and select Online Repair for a more thorough fix.

Frequently Asked Questions
Will repairing OneNote delete my local notebooks?
Running a Quick Repair or Online Repair through Windows settings generally does not delete personal files or notebooks. However, it is highly recommended to manually back up unsynced local notebooks before starting the repair process just in case.
What should I do if OneNote still crashes after an Online Repair?
If repairing the app does not work, try creating a new Windows user profile to see if the issue is tied to a corrupted user account. Alternatively, test OneNote by opening a completely new notebook to rule out file-specific corruption.
Why does OneNote say it has encountered a problem and must be closed?
This error typically triggers when application files become corrupted, a third-party add-in conflicts with the software, or a specific local notebook file is damaged, forcing the application to close itself to prevent further data corruption.
