Question details

The user needs to determine if a OneDrive ransomware notification email is authentic and wants to know the safe procedure to recover affected files without falling for scams.

How to Verify a OneDrive Ransomware Email and Safely Recover Files

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: The user received an email claiming their OneDrive files have been compromised by ransomware and is seeking instructions on how to proceed safely.
Observed behavior: The user is unsure whether the email is a legitimate alert from Microsoft or a phishing attempt, and requires the official steps for secure file recovery.

Before you start

Do not click any links or download attachments from the suspicious email, and never pay a ransom. Ensure you navigate directly to the official OneDrive website by manually typing the address into your web browser.

Solution 1Recommended

Verify the Alert and Restore Files via Official OneDrive

Bypass the potentially malicious email completely and check for official ransomware notifications directly within your secure OneDrive account to initiate the file restoration process.

Microsoft 365 includes built-in ransomware detection that will display an alert within the OneDrive web interface if an attack is detected. Relying on the web interface rather than email links prevents you from falling victim to phishing.

Sign in directly to OneDrive

Open your preferred web browser, type 'onedrive.com' into the address bar, and sign in to your Microsoft account. Do not use the login links provided in the suspicious email.

Check for the official notification

Look at the top of your OneDrive screen. If Microsoft 365 has genuinely detected ransomware, you will see a prominent banner stating 'Signs of ransomware detected'.

Start the recovery process

Click the 'Get started' button located on the official warning banner. This will redirect you to the 'Restore your OneDrive' page.

Verify your compromised files

Review the list of files identified as compromised. Confirm they are your files and note the date and time when the suspicious activity was recorded.

Restore your OneDrive

Select a safe date prior to the ransomware attack from the dropdown menu, and click 'Restore' to revert your entire OneDrive to that uncorrupted state.

Frequently Asked Questions

How can I easily tell if a OneDrive email is a phishing scam?

Legitimate Microsoft security emails usually come from domains like '@accountprotection.microsoft.com'. However, email addresses can be spoofed. The safest method is to ignore all links in the email and log directly into onedrive.com to see if an alert appears in your dashboard.

What is the 'Restore your OneDrive' feature?

It is a specialized Microsoft 365 recovery tool that allows users to undo all actions that occurred on both files and folders within the last 30 days. It is specifically designed to recover accounts from ransomware attacks or accidental mass deletions.

Can I recover ransomware-encrypted files if I don't have Microsoft 365?

Without a premium Microsoft 365 subscription, you do not have access to the automated ransomware detection or the bulk 'Restore your OneDrive' feature. You may have to manually check the version history of individual files to restore them one by one.
