Solution 1Recommended

Verify Your Billing Activity Directly via Microsoft

Bypass the email completely and check your official Microsoft account order history to confirm if any real charges were made.

Scammers rely on panic. By independently checking your official account dashboard, you can safely verify that the USD 660.99 charge is entirely fake and that your subscription is secure.

Open a Secure Browser Tab

Open a new window in your web browser and manually type in 'account.microsoft.com' to ensure you are visiting the legitimate Microsoft website.

Sign In to Your Account

Check Order History

Navigate to the 'Payment & billing' section, then click on 'Order history'. Review the recent transactions to verify that only your normal monthly charges exist.

Account Safe: If the USD 660.99 charge does not appear in your official Order History, the email you received is a confirmed phishing scam. Your account and funds are secure.

Solution 2

Report and Delete the Phishing Email

Safely remove the threat from your inbox and help email providers block the scammer.
