Fix OneDrive for Business Sign-In Throttling or Temporary Unavailable Error
Question details
The user cannot sign in to OneDrive for Business because of throttling or temporary-unavailable errors while other Microsoft 365 applications continue to work, blocking access to work files.
- Product
- OneDrive for Business / Microsoft 365
- Device & OS
- not provided
- Scenario
- The user is trying to sign in or synchronize OneDrive for Business to access work files, but the service is throttled or temporarily unavailable.
- Observed behavior
- OneDrive displays throttling or temporary-unavailable messages and blocks access, while other Microsoft 365 apps work normally.
Before troubleshooting, save the exact error page URL or message and confirm that other Microsoft 365 services are still responding. If the account is a work or school account, be ready to contact the Microsoft 365 administrator because tenant-level throttling often cannot be cleared by the end user.
Pause OneDrive Sync and Retry After the Throttle Window
Use this first when the error appears suddenly and you need quick access to OneDrive for Business.
Right-click the OneDrive cloud icon in the taskbar notification area and select Pause syncing for 2 hours or Exit.
Close the OneDrive app or browser tab, wait 30–60 minutes, then go to https://office.com and sign in to OneDrive again.
If access is urgent, open OneDrive on another trusted device or network, but avoid repeated high-volume retries that can extend throttling.
Have Your Microsoft 365 Administrator Review Tenant Throttling
Use this when the error persists because Microsoft 365 admin center diagnostics and support can identify tenant-level throttling.
Reduce High-Volume Sync to Prevent Future OneDrive Throttling
Use this after access is restored to avoid repeated throttling and keep synchronization within Microsoft limits.
Use WPS Office to Keep Working on Local Office Files While OneDrive Recovers
When OneDrive for Business is throttled or temporarily unavailable, WPS Office provides a free, lightweight way to open, edit, and save Word, Excel, and PowerPoint files locally with Microsoft Office format compatibility and a familiar interface.
- 1. Download WPS Office: Visit the official WPS Office download page and install WPS Office on your Windows, macOS, Android, or iOS device.
- 2. Open local Office files: Launch WPS Office and open the Word, Excel, or PowerPoint file you need from local storage instead of OneDrive.
- 3. Save in Microsoft-compatible formats: Edit the file and save it as DOCX, XLSX, or PPTX so it can be uploaded back to OneDrive when service is restored.
Frequently Asked Questions
Is OneDrive throttling caused by WPS Office?
No, OneDrive throttling is a Microsoft 365 service-side condition. WPS Office can open and edit local Office files, but it cannot change or fix a OneDrive tenant throttling state.
Why does OneDrive for Business show 'temporarily unavailable' when other Microsoft 365 apps work?
OneDrive and SharePoint Online throttle specific workloads to protect overall service performance. Other Microsoft 365 applications may remain available because they use separate service paths.
How long does OneDrive throttling usually last?
Temporary throttling can clear automatically within minutes or hours. If the error persists, an administrator should review service health and tenant activity and may need to open a Microsoft support request.
Can I prevent OneDrive for Business throttling?
You can reduce the chance of throttling by using selective sync, splitting large uploads or migrations into smaller batches, and avoiding repeated high-volume synchronization attempts.
What can I do if I need to work on files during a OneDrive outage?
Use local copies of your files and open them in WPS Office to edit Word, Excel, or PowerPoint documents. Save in Microsoft-compatible formats and upload them back to OneDrive when the service is restored.
