Frequently Asked Questions

What causes the 'high volume of requests' error in OneDrive?

This error is typically triggered when an automated script, continuous backup application, or rapid file-copying task sends too many requests to OneDrive servers in a very short time, resulting in a temporary anti-spam block.

Will I lose my files if my OneDrive account is blocked?

No, a temporary account restriction only prevents sign-in and syncing to protect the servers. Your files remain securely stored in the cloud and will be fully accessible once Microsoft reinstates your account.

How can I prevent OneDrive from blocking my account again?

To avoid future restrictions, limit the use of unauthorized third-party automated scripts for downloading or uploading files. If you are migrating large amounts of data, use official syncing tools and pace the transfer to avoid triggering traffic alerts.
