Solution 1Recommended

Verify the Alert via Direct Account Sign-In

The safest method to confirm a security alert is to bypass the email entirely and check your account status directly through the official website.

Phishing emails often use alarming subjects like 'Signs of ransomware detected' to panic users into clicking malicious links. Genuine Microsoft alerts will always reflect in your account dashboard when you sign in directly.

Open a Secure Web Browser

Launch your preferred web browser and open a new, clean tab. Do not use any links provided in the email.

Navigate to the Official Website

Manually type the official Microsoft 365 or OneDrive website address (e.g., onedrive.live.com or office.com) into the address bar and press Enter.

Sign In and Check for Alerts

Log in with your credentials. If the ransomware alert is genuine, you will see a prominent security notification or banner inside your OneDrive or Microsoft 365 dashboard asking you to take action.

Verify the Alert via Direct Account Sign-In

Alert Confirmed: If you see the warning inside your account dashboard after a direct sign-in, the alert is genuine and you should follow the on-screen prompts to secure your files.

Frequently Asked Questions

Why do official Microsoft emails sometimes go to the Junk folder?

Strict email spam filters or custom inbox rules can mistakenly flag legitimate security alerts as spam. This often happens because security alerts contain multiple links or use urgent language, which are traits commonly associated with phishing emails.

What should I do if the ransomware alert is actually a phishing email?

Do not click any links or download any attachments. Use your email provider's reporting tools to mark the message as phishing, then delete the email permanently to protect your account and computer.

Can I recover my files if my OneDrive is actually infected with ransomware?

Yes, Microsoft 365 provides a 'Files Restore' feature for OneDrive that allows you to undo all actions that occurred on both files and folders within the last 30 days, helping you recover from ransomware attacks.
