Question details
The user is unable to sync a OneNote notebook stored in OneDrive to the desktop application, receiving error code 0xE000006B blg57, despite the web version showing the latest changes.

- Product
- Microsoft OneNote, OneDrive
- Device & OS
- not provided
- Scenario
- Synchronizing a OneNote notebook stored in OneDrive using the desktop application.
- Observed behavior
- OneNote cannot connect to the server, halting sync and displaying error 0xE000006B blg57.
Log in to OneNote for the web and verify that all your recent changes are safely synced online. Copy any unsynchronized text from your desktop app to a temporary document to prevent data loss.
Clear the Local OneNote Cache
Clearing the local cache resolves server connection issues by forcing OneNote to redownload a fresh copy of your notebook from OneDrive.
Local cache corruption is a common cause for sync interruptions between the desktop app and OneDrive.
Close all open notebooks within the application and completely quit the OneNote desktop application.
Press Windows + R, type '%localappdata%\Microsoft\OneNote\16.0', and press Enter. Locate the folder named 'cache'.
Move the 'cache' folder to your desktop or rename it to 'cache.old' to force OneNote to rebuild it.
Restart your computer, launch OneNote, and open your notebooks directly from OneDrive to trigger a fresh sync.

Install the Latest OneNote Updates
Syncing issues are often patched in newer versions. Ensuring your app is fully up-to-date can resolve server connection errors.
Isolate the Affected Notebook
Determine if the error is specific to a single notebook or your entire OneDrive account to narrow down the troubleshooting scope.

Frequently Asked Questions
What does error 0xE000006B blg57 mean in OneNote?
This error indicates that the OneNote desktop application is having trouble communicating with the OneDrive server, preventing your local notebook from synchronizing with the cloud.
Will clearing my OneNote cache delete my notes?
Clearing the cache will not delete notes that have already been synced to OneDrive. However, any unsynchronized changes in your desktop app will be lost if you do not manually copy them somewhere else first.
Why does OneNote sync work on the web but not on the desktop app?
The web version accesses the data directly from the server. Desktop app sync issues usually stem from local cache corruption, outdated software versions, or local network configuration blocks.
