How to Fix OneNote Sync Error 0xE0000045 (Overwritten Changes)
Question details
The user needs to resolve an issue where OneNote fails to synchronize and eventually overwrites local desktop edits with the cloud version, resulting in data loss.
- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Attempting to synchronize recent local desktop notebook edits to the cloud.
- Observed behavior
- OneNote displays the message "OneNote is waiting to sync your changes" along with error code 0xE0000045 bbg1m. When the synchronization eventually resumes, the cloud copy overwrites the recent desktop edits.
Immediately copy any unsynchronized text or recent edits into a separate, offline text document (like a local Word or WPS Writer file) to prevent permanent data loss before attempting any further synchronization fixes.
Use Microsoft Diagnostic Tools and Escalate to Support
Because standard troubleshooting steps (like repairing Office or checking connectivity) often fail to resolve this persistent error, running advanced diagnostic tools with Microsoft Support is required.
Error 0xE0000045 with the code 'bbg1m' indicates a deeper synchronization state corruption. Technicians will likely need to remotely access the computer and run a specific Microsoft Diagnostic Tool to repair the corrupted sync state.
Visit the official Microsoft Support website and open a ticket regarding OneNote synchronization error 0xE0000045.
Inform the support agent that standard repairs have failed and request to run the advanced Microsoft Diagnostic Tool to repair the notebook's sync state.
If prompted, permit the support technician to securely remote into your desktop to identify the damaged notebook and allow the repair tool to run until no errors remain.
Record every support incident number provided during the session. If the synchronization problems continue, use these numbers to request an immediate escalation.
Attempt to Recover Overwritten Changes
If the sync error has already overwritten your local desktop edits, you may be able to recover the lost data using OneNote's built-in history features.
Looking for a Stable and Free Office Solution?
If persistent Microsoft Office synchronization errors are disrupting your workflow and causing data loss, consider switching to WPS Office. It provides a lightweight, highly compatible, and completely free alternative with reliable local saving and secure cloud backup options.
- 1. Download and Install: Visit the official WPS website to download the free installation package and follow the on-screen instructions.
- 2. Open Existing Documents: Launch WPS Office and open your existing Microsoft Office files directly without worrying about formatting issues.
- 3. Enable Secure Cloud Sync: Sign in to a WPS account to enable reliable automatic backups and seamless cross-device synchronization.
Frequently Asked Questions
What does OneNote error code 0xE0000045 mean?
This error code indicates that the OneNote desktop client is unable to successfully communicate its local changes to the cloud server, causing the sync engine to stall and sometimes overwrite local edits with the older cloud version.
Why did my local OneNote edits disappear after synchronization?
When the sync state becomes corrupted, the server copy may incorrectly be identified as the most up-to-date version. As a result, OneNote overwrites the local cache with the cloud copy, leading to apparent data loss of your recent desktop changes.
What is the 'bbg1m' code associated with this error?
The tag 'bbg1m' is a specific diagnostic code generated by OneNote. It helps Microsoft Support technicians pinpoint the exact module or state failure during remote diagnostics to apply the correct repair tool.
