How to Repair a OneNote Section That Has Not Finished Syncing
Question details
The user is trying to resolve an issue where a OneNote backup section cannot be opened or have its data extracted because it is stuck with a message stating it has not finished syncing.

- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Attempting to open, restore, or extract data from a local OneNote backup section file.
- Observed behavior
- A synchronization error message appears stating the section has not finished syncing, which blocks the file from opening and prevents data extraction.
Ensure you have completely exited the OneNote application and created a secure copy of your backup file in a different folder before proceeding with the command-line repair.
Use the Windows Run Dialog to Force Repair
Use the built-in OneNote command-line switch to force a structural repair on the corrupted or indefinitely syncing section file.
This method utilizes the executable parameters available for the desktop version of OneNote. It attempts to bypass the synchronization block by manually rebuilding the section file's structure.
Close the OneNote application entirely. Ensure it is not running in the system tray or background.
Navigate to the folder containing your problematic OneNote backup file. Copy the file and paste it into the same or a different folder to serve as a safe backup.
Hold down the 'Shift' key on your keyboard, right-click the original backup file, and select 'Copy as path' from the context menu.
Press 'Windows + R' to open the Run dialog box. Type 'onenote.exe /forcerepair ' (ensure there is a space at the end) and press 'Ctrl + V' to paste the copied file path.
Press 'Enter' or click 'OK'. Wait for the command line process to execute and finish repairing the file, then attempt to open the section again.

Frequently Asked Questions
Why does my OneNote section say it has not finished syncing?
This usually happens when an internet connection drops during a sync process, OneDrive storage is full, or the local cache file becomes corrupted before the changes can be properly uploaded to the cloud server.
Does the forcerepair command work for OneNote for Windows 10?
No. The 'onenote.exe /forcerepair' command is exclusive to the traditional desktop application of OneNote. OneNote for Windows 10 is built on the Universal Windows Platform (UWP) and does not support traditional .exe command-line arguments.
What happens if the forcerepair command only opens the app but doesn't fix the section?
If OneNote just launches normally without fixing the file, ensure you have included a space between '/forcerepair' and the file path. Also, ensure the file path is enclosed in quotation marks if it contains spaces.
Will forcing a repair delete any of my OneNote notes?
The repair command attempts to salvage and restructure the file so it can be opened. While it tries to retain all information, severely corrupted pages might be lost. This is why you must always create a copy of the backup file before running the command.
