How to Fix OneNote Synchronization Errors After Changing Notebook Colors
Question details
Users experience offline-save and synchronization errors when changing a notebook's color in OneNote.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10, macOS
- Scenario
- Customizing the appearance of notebooks by assigning specific colors while relying on cloud synchronization.
- Observed behavior
- Changing the notebook color to anything other than gray causes the application to stop syncing. Reverting the notebook color back to gray temporarily restores synchronization functionality.
Before applying any application resets, ensure you manually copy and paste any unsynchronized notes into a separate local document to prevent permanent data loss.
Reset the OneNote Application via Windows Settings
Resetting the OneNote app clears temporary application data and resolves software glitches that cause the synchronization blockage.
This process will reset the app's local settings. Any notes that have successfully synced to the cloud will automatically reload once you sign back in.
Press the Windows key + I on your keyboard to open Windows Settings, then click on the 'Apps' category.
Select 'Apps & features' from the left sidebar, scroll down the application list to find 'OneNote for Windows 10', and click on it to reveal more options.
Click the 'Advanced options' link located directly under the OneNote application name.
Scroll down to the Reset section and click the 'Reset' button. Confirm the action in the pop-up dialog box to clear the application's local data.
Restart your computer. Open OneNote, sign in to your Microsoft account, and verify if the synchronization error is resolved.

Apply Notebook Color Changes Using OneNote 2016
Using the classic OneNote 2016 desktop application can force an automatic color assignment that bypasses the bug present in the Windows 10 app version.
Perform a Clean Boot to Isolate Software Conflicts
A clean boot starts Windows with a minimal set of drivers and startup programs, helping you identify if a background service is interfering with OneNote's sync engine.

Frequently Asked Questions
Why does changing a OneNote notebook color cause it to stop syncing?
This is a known bug in specific versions of OneNote for Windows 10 and OneNote for Mac. The application occasionally fails to correctly update the customized color metadata to the OneDrive cloud servers, which stalls the entire synchronization process and results in an offline-save error.
Will I lose my notes if I reset the OneNote application?
Yes, any local edits or new notes that have not successfully synced to the cloud will be permanently lost during a reset. You should always manually copy and paste unsynchronized text into a temporary local document (like Word or Notepad) before initiating an app reset.
Does this synchronization error also occur on Mac devices?
Yes, many users have reported the identical problem on macOS platforms. Changing the notebook color interrupts the sync engine on Macs, and temporarily switching the color back to gray often restores normal synchronization.
How do I access OneNote 2016 if it is not installed on my computer?
OneNote 2016 (now officially referred to simply as 'OneNote') is the classic desktop version. It can be downloaded and installed for free directly from the Microsoft Store or the official Microsoft Office website, independent of the Windows 10 specific app.
