How to Fix OneDrive Reparse Point Errors 0x80071128 and 0x80071129
Question details
The user needs to identify and resolve the root cause of OneDrive reparse point errors during mass file synchronization.

- Product
- OneDrive
- Device & OS
- Windows
- Scenario
- Synchronizing a large batch of files to OneDrive where sync fails without a clear error icon on the problematic file.
- Observed behavior
- Synchronization halts with error codes 0x80071128 or 0x80071129, indicating an invalid reparse-point buffer, making it difficult to find the corrupted item.
Ensure your Windows operating system is fully updated and check that your OneDrive client is running the latest version before proceeding with profile troubleshooting.
Test Synchronization with a New Local Windows User Profile
Create a separate local Windows profile to determine if the issue stems from a corrupted OneDrive profile or the cloud data itself.
Because reparse point errors often stem from corrupted user profile caches rather than actual cloud data, isolating the synchronization process in a fresh Windows environment is the safest diagnostic step.
Click the Start menu, open 'Settings', navigate to 'Accounts', and select 'Family & other users' from the left sidebar.
Click 'Add someone else to this PC'. When prompted, select 'I don't have this person's sign-in information', then choose 'Add a user without a Microsoft account' to create a local profile.
Log out of your current Windows account and log into the newly created local account. Open the OneDrive application from the Start menu and sign in with your credentials.
Allow OneDrive to sync. If the synchronization completes without error codes 0x80071128 or 0x80071129, your original Windows user profile is likely corrupted and needs to be rebuilt.

Run CHKDSK to Repair File System Corruption
Use the Windows Check Disk utility to scan and repair underlying file system corruption that may be causing invalid reparse-point buffer errors.
Maintain Your Productivity with WPS Office During Sync Errors
If OneDrive synchronization issues are disrupting your daily document workflow, consider using WPS Office. It is a highly compatible, lightweight, and free alternative that ensures your document editing remains uninterrupted while you resolve cloud storage errors.

Frequently Asked Questions
What do OneDrive error codes 0x80071128 and 0x80071129 mean?
These error codes indicate that the data in the reparse point buffer is invalid. This issue is typically caused by corrupted files, damaged local user profiles, or broken directory junctions on your Windows file system.
Will reinstalling the OneDrive app fix these reparse point errors?
Reinstalling OneDrive generally does not resolve this issue because the root cause usually lies within a corrupted local Windows user profile or hard drive file system errors. Testing with a new local user account is a much more effective diagnostic step.
How do I identify the exact file causing the OneDrive synchronization error?
When synchronizing thousands of files, finding the specific corrupted item can be difficult if there is no red error cross. You can check the OneDrive diagnostic logs located in your system's AppData folder. If the logs are overly complex, contacting Microsoft Support for advanced log analysis is highly recommended.
