Fix OneDrive Restore Stuck at 0 Percent with Access Denied Errors
Question details
The user needs to resolve an issue where a OneDrive file restoration process is frozen at 0 percent and generating access-related errors in the log.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to restore a large volume of data using the OneDrive restoration feature.
- Observed behavior
- The restore progress remains entirely stuck at 0 percent for hours, and the restoration log displays 'Access is denied' and 'Log is truncated' messages.
Before proceeding, do not attempt to forcefully stop or restart the restoration process yourself, as abruptly interrupting a stalled server-side operation can lead to further data inconsistencies.
Contact Microsoft Support via the Tenant Administrator
Because the restore process is encountering backend access errors and is completely stalled, intervention from Microsoft Support is necessary to safely manage or cancel the process.
When a OneDrive restore process gets stuck at 0% and the logs show 'Access is denied' or 'Log is truncated', it typically indicates server-side permission conflicts, timeouts, or backend authentication issues associated with processing large datasets. This process will not resume normally on its own.
Contact your organization's Microsoft 365 tenant administrator, as standard users cannot open backend support tickets.
Have the administrator log into the Microsoft 365 admin center using their administrative credentials.
Navigate to the 'Support' section in the left-hand menu and select 'New service request'.
Provide the support team with the error logs and ask them to determine whether the stuck restoration can be safely canceled or forced to resume from the backend.

Frequently Asked Questions
Why does my OneDrive restore log say 'Access is denied'?
This error typically occurs during large data restorations when backend authentication tokens expire or there are permission conflicts preventing OneDrive from accessing, overwriting, or recovering specific files.
Can I just cancel the OneDrive restore if it is stuck?
It is not recommended to forcefully cancel a stuck restoration yourself, especially if logs show active backend errors. Contacting Microsoft support ensures the process is halted safely without corrupting your existing data or causing sync conflicts.
How long does a normal OneDrive restore take?
A normal restore depends on the amount of data being processed. Small restores can take just a few minutes, while massive datasets might take several hours. However, if progress remains exactly at 0% for hours while displaying error logs, the process is stuck.
What does 'Log is truncated' mean in OneDrive?
This message indicates that the error log file has exceeded its maximum allowed size limit and was cut off. This usually happens when the system encounters too many continuous errors, such as repeatedly failing to access files during a stalled restore.
