Users need to resolve unusually long wait times when attempting to sign in to OneDrive or synchronize files.

How to Fix Slow OneDrive Sign-In and Synchronization Issues

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Attempting to log into a OneDrive account or update local file changes to the cloud service.
Observed behavior: The account sign-in process and background file synchronization take an unusually long time to complete or appear stuck.

Before you start

Ensure your device is connected to a stable and fast internet connection, as poor local network performance can directly bottleneck your cloud synchronization speed.

Solution 1Recommended

Check the Microsoft 365 Service Health Dashboard

Verify if the delay is caused by an ongoing Microsoft server outage rather than a local device issue.

Often, unusually slow performance is not caused by your local machine or network. It is frequently the result of a known service issue on Microsoft's end affecting their applications and cloud environments, including OneDrive and OneNote.

Visit the service status page

Open your preferred web browser and navigate to the official Microsoft Service Health Status page at https://portal.office.com/ServiceStatus.

Review current incidents

Look for any reported outages, warnings, or degraded performance indicators related to OneDrive or general Microsoft 365 services.

Monitor and wait

If an active issue is reported by Microsoft, there is no action required on your device. Wait for Microsoft engineers to resolve the server outage, and try signing in or syncing your files later.

Check the Microsoft 365 Service Health Dashboard

Monitoring Real-Time Updates: You can keep the Service Health dashboard tab open and refresh it periodically to monitor real-time updates regarding the server repair status.

Frequently Asked Questions

Why is my OneDrive taking so long to sync files?

Slow sync speeds can be caused by Microsoft 365 server outages, a weak local internet connection, syncing overly large files simultaneously, or restrictive bandwidth limits set within the OneDrive desktop app settings.

Can I speed up OneDrive synchronization manually?

Yes, you can speed up syncing by removing bandwidth limits. Click the OneDrive icon in your taskbar, go to Settings, navigate to the 'Network' or 'Sync and Backup' tab, and ensure both upload and download rates are not arbitrarily limited.

What should I do if the Microsoft Service Status shows no issues, but syncing is still slow?

If the Microsoft servers are operating normally, try pausing and then resuming the sync from the OneDrive taskbar menu. You can also try completely closing and restarting the OneDrive application, or restarting your local network router to rule out connectivity drops.

Is there a limit to the file size I can sync on OneDrive?

Yes, OneDrive supports syncing individual files up to 250 GB in size. However, exceptionally large files or folders with thousands of small items will naturally take significantly longer to process and upload, depending on your internet service provider's upload speeds.
