1] Check internet connection
It is the first thing you must check since synchronization requires a valid internet connection. To verify your internet connection, do the following:
- Press Win+R to open the Run prompt.
- Type ping ping 8.8.8.8 -t and click the OK button.
Your internet connection is fine if you see consistent ping times. However, you need to change the internet connection if you see any other message.
Bonus tips: If you have enabled VPN or proxy, you can disable them temporarily. At times, VPN or proxy servers could cause internet connection issues.
2] Verify OneDrive service health

OneNote uses OneDrive to synchronize data. If OneDrive is down, your notebooks cannot be synchronized. That is why you can head to the portal.office.com and check if there is any issue with OneDrive or not. If yes, it is better to wait for some time.
3] Sync manually

Sometimes, OneNote might not synchronize your notebooks automatically for various reasons. It could be due to a poor internet connection, a corrupted system file, etc. In such situations, you need to synchronize them manually. For that, do the following:
- Open the OneNote app on your computer.
- Click on File > Info.
- Click the View Sync Status button.
- Select the notebook you want to synchronize or are having problems with.
- Click the respective Sync Now button.
It is very important to choose Sync automatically whenever there are changes option before closing the window so that you do not need to go through all those steps every time you make a change.
4] Sign out and re-sign into OneNote

If your OneNote or Microsoft account has some internal issues, you could face the same problem. That is why it is suggested that you sign out of your account and re-sign into it. For that, do the following:
- Open the OneNote app first.
- Click on File > Account.
- Click the Sign out button.
- Click on the Yes button to confirm.
- Click the Sign in button and enter your login credentials.
Once done, open the same notebook and edit a few words or so.
5] Create new section and copy data

At times, the current section or pages may not be synchronized due to some add-ins. In that case, you can create a new section and copy the data. For that, follow the following steps:
- Open the OneNote app.
- Select the notebook first.
- Click the plus icon to create a new section.
- Enter a name with copy suffix to recognize it quickly.
- Open the original section and right-click on the desired page.
- Select the Copy option.
- Open the new section.
- Right-click on the pages section and select the Paste option.
After that, check whether the problem is resolved.
6] Clear OneNote cache

To delete the OneNote cache, follow these steps:
- Open the File Explorer on your computer.
- Navigate to this path: C:\Users\[username]\AppData\Local\Microsoft\OneNote\16.0
- Right-click on the Cache folder and select the Delete option.
- Confirm the removal.

OneNote Diagnostic Tool is a one-stop solution for all common synchronization problems. It runs smoothly on Windows 11 and Windows 10.

Therefore, you can head to Microsoft.com and download the diagnostic tool first. Then, run the MSI package to install it. Then, open the app and follow the screen instructions.
