OneDrive automatically moved my files to the Recycle Bin without permission

Hello,

A large number of files and folders suddenly disappeared from my OneDrive account without my permission or prior notification.

I found them in the Recycle Bin and managed to restore them.

This issue is not related to insufficient storage space, as my account has sufficient available storage.

I would like to understand what caused these automatic deletions and how to prevent this from happening again.

Thank you.

    Dear Yacoby,

    I'm glad you were able to restore your files. Seeing a large number of them disappear without warning is understandably worrying. As a forum moderator, I am not able to review your OneDrive activity to confirm what caused the deletion. My role here is limited to providing general guidance you can apply from your side.

    OneDrive doesn't delete files on its own. When files disappear in bulk, it's usually because they were deleted or moved on another device that syncs with your OneDrive, removed from a shared folder by someone else with access, or affected by a cleanup, backup or sync tool on one of your computers. Moving files out of the OneDrive folder on a PC also looks like a deletion to OneDrive. The activity feed is the best way to see what happened here:

    1. Sign in at onedrive.com.
    2. Go to Settings > Restore OneDrive.
    3. Look at the activity chart and feed around the time the files disappeared to see when the deletion happened.

    To help prevent this from happening again:

    • Review your devices: Check every computer and phone signed in to your OneDrive, including old ones, and remove any you no longer use.
    • Check other software: Make sure no cleanup, backup or other sync tool is set to manage your OneDrive folder.
    • Secure your account: If you see any sign-in activity you don't recognize, change your password and turn on two-step verification.
    • Keep a separate backup: For important files, a backup outside OneDrive gives you an extra layer of protection.

    For a work or school account, your IT administrator can also review the audit records to see which user or device made the deletion.

    I hope this helps you find the cause. Looking forward to your reply.
