Solving OneNote Syncing Issues: Step-by-Step Troubleshooting Guide

OneNote is a powerful tool for organizing and managing personal and professional tasks. Whether you use it for note-taking, creating to-do lists, or collaborating with team members, OneNote can significantly enhance your productivity. However, encountering syncing problems can be frustrating and hinder your ability to access your notes across devices. In this guide, we will provide step-by-step solutions to common OneNote syncing issues, helping you get back to peak performance with minimal hassle.

Understanding OneNote Syncing Issues

Before diving into the troubleshooting steps, it's important to understand the common reasons behind OneNote syncing problems. These can include:

  1. Internet connectivity issues
  2. Account problems
  3. Software conflicts
  4. Corrupted cache files

Identifying the root cause of the syncing problem is crucial in finding an effective solution. Let's explore the troubleshooting steps you can take.

Troubleshooting OneNote Sync Errors

Step 1: Check Your Internet Connection

The first step in troubleshooting OneNote syncing issues is to ensure that you have a stable internet connection. Follow these steps:

  1. Check your Wi-Fi or network connection settings.
  2. Verify that you can access other websites or online services without any problems.
  3. If you're using a mobile device, try switching to a different network or using cellular data.

If your internet connection is unstable or unavailable, it's likely the cause of the syncing problem. Resolve the connectivity issue before proceeding further.

Step 2: Sign Out and Sign Back In

Signing out of your OneNote account and signing back in can refresh the authentication tokens and resolve syncing errors. Here's how to do it:

  1. Open OneNote and navigate to the account settings.
  2. Select the option to sign out of your account.
  3. After signing out, close OneNote completely.
  4. Open OneNote again and sign back in using your credentials.

This simple step can often resolve minor syncing issues by reestablishing a secure connection to the OneNote servers.

Step 3: Update OneNote and Operating System

Outdated software versions can sometimes lead to syncing conflicts. Ensure that both your OneNote application and operating system are up to date. Follow these steps:

  1. Check for updates in the Microsoft Store or your device's app store.
  2. If updates are available, install them and restart your device if necessary.
  3. Additionally, check for system updates in your device's settings and install any available updates.

Keeping your software up to date ensures compatibility and can often resolve syncing problems.

Step 4: Clear OneNote Cache

The OneNote cache stores temporary files that can sometimes become corrupted or outdated, leading to syncing issues. Clearing the cache can resolve these problems. Here's how:

  1. Close OneNote completely.
  2. Press Windows Key + R to open the Run dialog.
  3. Type %localappdata%\Microsoft\OneNote and press Enter.
  4. Locate and delete the contents of the "16.0" or "15.0" folder.
  5. Restart your device and open OneNote again.

Clearing the cache will force OneNote to rebuild its cache files, potentially resolving any syncing problems caused by corrupted or outdated cache files.

Step 5: Disable Add-ins or Antivirus Software

Third-party add-ins or antivirus software can sometimes interfere with OneNote syncing. Temporarily disabling them can help identify if they are causing the problem. Follow these steps:

  1. Open the settings or preferences of your antivirus software.
  2. Look for an option to disable or pause the software temporarily.
  3. If you have any OneNote add-ins installed, open OneNote, go to the Add-ins menu, and disable them.
  4. Restart OneNote and check if the syncing problem persists.

If disabling the add-ins or antivirus software resolves the syncing issue, consider updating or reinstalling them to ensure compatibility with OneNote.

Advanced Troubleshooting Options

If the basic troubleshooting steps didn't resolve the syncing problem, you can try more advanced options:

Repair OneNote Installation

If OneNote is still not syncing correctly, you can repair the installation using the built-in repair function or via the Control Panel. Here's how:

  1. Close OneNote completely.
  2. Open the Control Panel and navigate to the "Programs" or "Apps" section.
  3. Find Microsoft OneNote in the list of installed programs.
  4. Select the option to repair the installation.
  5. Follow the on-screen instructions to complete the repair process.

Repairing the OneNote installation can fix any underlying issues that may be preventing proper syncing.

Reset OneNote Application

If all else fails, you can try resetting the OneNote application. This will clear any persistent configuration or settings causing syncing errors. Follow these steps:

  1. Close OneNote completely.
  2. Open the Windows Settings and navigate to the "Apps" or "Apps & Features" section.
  3. Find Microsoft OneNote in the list of installed apps.
  4. Select the option to reset the application.
  5. Confirm the reset and wait for the process to complete.

Resetting the OneNote application will restore it to its default settings, potentially resolving any complex syncing issues.


OneNote syncing problems can be frustrating, but with the troubleshooting steps outlined in this guide, you can resolve them and regain productivity. Remember to take your time and follow the instructions carefully. If the issue persists, don't hesitate to seek further assistance from Microsoft support or online forums dedicated to OneNote.

Ensure that you regularly back up your important notes to avoid data loss in case of syncing problems. With these solutions at your disposal, you can make the most of OneNote's powerful features without worrying about syncing errors.


A: Some common error messages include "We can't sync this notebook," "There was a problem syncing this section," or "OneNote needs a password to sync this notebook." These messages often indicate issues with internet connectivity, authentication, or conflicts with third-party software.

Q: How can I prevent OneNote syncing errors in the future?

A: To prevent syncing errors, ensure that you have a stable internet connection, regularly update OneNote and your operating system, and avoid using incompatible or outdated add-ins. Additionally, consider backing up your important notes to an external location to safeguard against potential syncing problems.

Q: Can I recover lost data due to OneNote syncing problems?

A: If you've lost data due to syncing problems, check the "Notebook Recycle Bin" in OneNote to see if the deleted notes are recoverable. If not, you can try restoring a previous version of the notebook from your device's backup or using file recovery software. However, it's essential to regularly back up your notes to avoid data loss in the first place.

Q: Why is OneNote syncing slow?

A: Slow syncing in OneNote can be caused by a variety of factors, including a weak internet connection, large file sizes, or server issues. To improve syncing speed, ensure a stable internet connection, optimize file sizes by splitting large notebooks into smaller sections, and check for any known server issues on Microsoft's support website.

Q: Can I use OneNote offline?

A: Yes, you can use OneNote offline. When you're offline, any changes you make to your notes will be synced once you regain an internet connection. However, note that some features, such as real-time collaboration, may be limited or unavailable offline.
