Question details

Users are receiving email or system warnings stating that a large number of files have been deleted from OneDrive, even though their OneDrive Recycle Bin is completely or nearly empty.

Product: OneDrive
Device & OS: not provided
Scenario: Receiving an unexpected file deletion alert from OneDrive and trying to verify if files are actually missing.
Observed behavior: The system sends automated file deletion warnings, but checking the Recycle Bin reveals no corresponding deleted files, causing confusion and security concerns about potential phishing or account compromise.

Before you start

Do not click on any links or download attachments in the warning email, as it could be a phishing attempt spoofing a Microsoft address.

Solution 1Recommended

Check OneDrive Synchronization and Folder Backup Activity

Verify if the deletion alert was triggered by automated background processes like game saves or application syncs rather than actual user deletions.

OneDrive folder backup can sometimes detect routine background file replacements as mass deletions. This is especially common with PC game save directories or third-party applications that constantly overwrite temporary files.

Access OneDrive directly

Open your web browser and manually type in onedrive.live.com to log into your account directly, bypassing any links provided in the warning email.

Review recent file activity

Navigate to the OneDrive settings menu, click on 'Options', and select 'OneDrive activity' to view a log of recent file changes and syncs.

Adjust folder backup settings

Check your PC folder backup settings in the OneDrive desktop app. If you notice game saves or temporary application files triggering the alerts, consider excluding those specific folders from your OneDrive backup.

Solution 2

Verify Account Security and Sign-in Activity

Ensure the warning is not the result of unauthorized account access or part of a phishing campaign by checking your Microsoft account security.

Frequently Asked Questions

Why did I get a OneDrive deletion warning if I didn't delete anything?

This often happens due to background folder backups. For example, PC games overwriting save files or automated applications moving temporary files rapidly can trigger OneDrive's mass deletion detection, even if actual files aren't in the Recycle Bin.

Could the OneDrive deletion email be a scam?

Yes, phishing emails frequently spoof official Microsoft addresses to steal your login credentials. You should always verify warnings by navigating directly to account.microsoft.com or your OneDrive app instead of clicking any links in the email.

How do I stop false OneDrive deletion alerts?

You can resolve this by reviewing your PC folder backup settings within the OneDrive app. Excluding folders that constantly generate or overwrite temporary files, such as specific game directories, will prevent these automated warnings.
