How to Monitor OneDrive Sync Health Across a Microsoft 365 Tenant
Question details
Administrators need to monitor OneDrive synchronization activity, identify delayed sync operations, and measure backed-up data across the organization after a large data migration.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Tracking organization-wide OneDrive sync status and diagnosing delayed syncs after moving massive volumes of data.
- Observed behavior
- A direct real-time tenant-wide synchronization load view is not available, requiring alternative methods to review sync health and errors.
Ensure you have global administrator or SharePoint administrator privileges in the Microsoft 365 admin center to access tenant-wide synchronization reports.
Check OneDrive Sync Reports in the Microsoft 365 Admin Center
Use the built-in sync reports to review synchronization health, spot errors, and track device sync status across your organization.
While OneDrive does not offer a real-time tenant-wide sync load dashboard, the Microsoft 365 admin center provides comprehensive sync health reports. These reports help identify which devices are experiencing sync errors and track the status of Known Folder Move deployments.
Log in to the Microsoft 365 admin center using your administrator credentials.
Navigate to the 'Health' section and select 'OneDrive sync' (or access it via the SharePoint admin center depending on your tenant setup).
If you are setting this up for the first time, enable the OneDrive sync health dashboard and deploy the necessary Group Policy or Intune settings to allow client devices to report their sync status.
Review the dashboard metrics to identify devices with sync errors, monitor delayed syncs, and verify the status of backed-up company data.

Contact Microsoft Support for Advanced Diagnostics
If you need deeper activity logs or payload information after moving massive data (like 150 GB), Microsoft support can extract advanced telemetry.

Frequently Asked Questions
Can I monitor OneDrive sync load in real time?
No, OneDrive does not currently provide a direct real-time tenant-wide synchronization load view. Administrators must rely on the OneDrive sync health reports in the Microsoft 365 admin center, which aggregate data periodically.
Why are large data migrations causing delayed syncs in my tenant?
Moving extensive amounts of data (such as 150 GB) at once can throttle the OneDrive sync client, as it must process file metadata, handle upload constraints, and check for conflicts. Keeping devices powered on helps the app gradually process the backlog.
How do I measure the total backed-up company data on OneDrive?
Administrators can view storage usage metrics in the Microsoft 365 admin center under 'Reports' > 'Usage', then select 'OneDrive' to see active files, storage consumed, and overall backup adoption across the tenant.
