What Causes Sync Issues?

The OneNote not syncing error can occur for various reasons. Here are the most common reasons why OneNote is not syncing:

  • Poor Internet Connection: One of the most common causes of the OneNote not syncing error is a poor or unstable internet connection. If your connection is weak, it may not be strong enough to support syncing and may cause the error to occur. Slow internet speeds or network disruptions can cause syncing problems.
  • Onenote Server Issues: Another common cause of the OneNote not syncing error is server issues. Sometimes, the OneNote server may experience downtime or maintenance issues, causing syncing problems. If the server is down or not working correctly, you may be unable to sync your notes to the cloud or other devices.
  • Outdated Software or Apps: Outdated versions of OneNote or other software and apps can also cause syncing problems. If you’re using an outdated version of OneNote, it may not be compatible with your operating system or other software, causing syncing errors. Similarly, if you’re using an outdated version of other apps or software that are required for syncing, it may cause the error to occur.

Check OneNote’s Sync Settings

To troubleshoot OneNote’s syncing issues, it is essential to ensure the sync settings are correctly set up. If automatic syncing fails, it could be due to incorrect settings. The steps to check and adjust sync settings differ between OneNote for Windows 10 and OneNote for Microsoft 365.

For OneNote App for Windows 10

1. Open OneNote’s More menu (three dots at the left corner of the window) and select Settings.

Check the OneNote Service Status

To start with, it is recommended to confirm whether a server-related problem is preventing OneNote from syncing. You can achieve this by opening OneNote Online and verifying if the content is current. If not, go to your web browser’s Office Service Status page to check for any issues.

If any problems are listed next to Office for the Web (Consumer), it is necessary to wait for Microsoft to resolve them. Additionally, error codes 0xE000078B and 0xE4020040 in OneNote could signify problems with the OneNote servers.

Update OneNote to the Latest Version

It must be updated to the latest version to address the issue of OneNote not syncing. Follow the tutorial below:

1. Open the Windows 10 Start menu and select Microsoft Store.

select microsoft store

2. Click “See more” in the top-right corner of the popup window, then select “Download and updates.”

3. Click “Get updates.”

Once you have completed the update, relaunch OneNote to verify whether the syncing problem has been resolved.

3. Delete the files or folders you do not want to save.

Solve Content Sync Conflict

Version conflict may arise when more than one user edits the same part of a page in OneNote. To avoid data loss, OneNote creates multiple copies of the page, which can lead to OneNote not syncing. Here is the tutorial to resolve content sync conflicts:

  1. If you see a yellow info bar, click on it to check the conflict message.
  2. Copy the content from the temporary page that shows the error and paste it on the primary page.
  3. Right-click on the page with the error and delete it.

After completing these steps, check if the OneNote sync issue is resolved.

Copy to New Section and Sync

When a particular notebook section fails to sync with OneNote Online or other devices, copying the data to a new section can resolve the issue. The 0xE000005E error code often accompanies this problem.

Here are the steps to follow:

  1. Go to the OneNote sidebar and create a new section for the notebook (use the Add section option).
  2. Right-click on each page of the problematic section and choose Move/Copy.
  3. Select the new section and click on Copy.
  4. If the new section starts syncing correctly, you can remove the old section and rename the new one with the same name.

If these methods fail, you can follow the steps below to resolve the issue:

  1. Go to the folder where your OneNote notebooks are stored. Typically, you can find it at: C:/Users/username\Documents\OneNote Notebooks.
  2. Find and copy the folder that contains the data of the affected notebook.
  3. Press Win + R to access the system’s root location. Type “%systemroot%” and hit Enter.
  4. Copy then paste the folder into the root location.

  6. Double-click the Notebook.onetoc2 file to open it using OneNote.

Improve Disk Space

The error codes 0xE0000796 (Quota Exceeded) and 0xE00015E0 can occur in OneNote due to insufficient storage space in OneDrive or SharePoint. To resolve this, you can delete or optimize existing backups to take up less space.

  1. Open OneNote and click on the “File” tab in the top left corner >> Click “Options.”
  2. In the “OneNote Options” window, click “Save & Backup” in the left-hand menu.
  3. Move to the “Optimizing files” section and click “Optimize All Files Now.”

That’s it! Once the optimization process is complete, you should have more space on your device, and your OneNote files should run more smoothly.
