How to Fix Multiple OneDrive or SharePoint Sync Errors in Bulk

Product: OneDrive and SharePoint
Device & OS: not provided
Scenario: Experiencing widespread sync failures across a large number of files simultaneously.
Observed behavior: Synchronization problems are reported for multiple files in bulk, making manual individual file repair inefficient and time-consuming.

Before you start

Ensure you have a stable internet connection and that your OneDrive application is fully updated to the latest version before attempting bulk repairs.

Solution 1Recommended

Use the OneDrive Built-in Repair Tool

The most efficient way to clear corrupted states and rebuild synchronization for multiple files at once.

Instead of resolving errors one by one, Microsoft provides a built-in diagnostic tool specifically designed to handle bulk synchronization failures by completely resetting the sync connection.

Open OneDrive Sync Problems

Right-click the OneDrive or OneDrive for Business icon located in the Windows notification area (system tray) and select 'View sync problems'.

Initiate the Repair Process

If multiple errors are reported in the dialog box, click the 'Repair' button. This will automatically clear the current sync state and begin rebuilding synchronization for all files.

Wait for Re-sync

Allow OneDrive some time to rebuild the synchronization. Do not restart your computer or disconnect from the internet until the process is complete.

OneDrive for Business: The Repair option is particularly prominent and effective in the OneDrive for Business sync client when dealing with extensive organizational file disruptions.

Solution 2

Fix Unsupported Characters and Paths in Bulk

Resolve bulk errors caused by widespread naming convention violations that prevent files from syncing.

Solution 3

Use PowerShell for SharePoint Bulk Operations

Ideal for SharePoint administrators needing to diagnose or reset sync states across an organization.

Frequently Asked Questions

Why are so many OneDrive files failing to sync at once?

Bulk sync failures usually happen due to widespread unsupported characters in file names, directory path lengths exceeding the 400-character limit, unsupported file formats, or a corrupted local OneDrive sync cache.

Will repairing OneDrive delete my local files?

No, using the built-in Repair tool in OneDrive will not delete your local files. It safely disconnects the current problematic sync state and rebuilds the connection to resolve conflicts.

Can I choose which folders to sync to avoid bulk errors?

Yes, you can use the Selective Sync feature. Click the OneDrive icon, go to Settings > Account > Choose folders, and uncheck the problematic folders to stop them from causing sync errors on your local device.
