Observed behavior
A potentially fraudulent $600 charge or invoice is presented to the user, causing concern over its legitimacy and fear of unauthorized billing.
Before you start

Do not click on any links, open any attachments, or call any phone numbers provided in the suspicious invoice email. Always navigate to the official Microsoft website directly through your browser to check your account status.

Solution 1Recommended

Verify the Invoice and Cancel Subscriptions in Your Microsoft Account

Check your official Microsoft account to see if the $600 charge is legitimate and manage any active subscriptions.

Scammers often send fake invoices to trick users into calling a fraudulent support number or clicking malicious links. The only definitive way to verify a real Microsoft purchase is through the official Microsoft account dashboard.

1
Go to Microsoft Services

Open your web browser and manually type 'https://account.microsoft.com/services' into the address bar.

2
Sign In

Log in using the Microsoft account email address associated with the supposed charge.

3
Review Subscriptions

Review the 'Services & subscriptions' page for any active Microsoft 365 subscriptions.

4
Cancel Unauthorized Charges

If you see a subscription you did not authorize, click 'Manage' next to it, and select 'Cancel subscription' or 'Turn off recurring billing'.

5
Identify the Scam

If the $600 subscription is not listed in your account, the invoice you received is almost certainly a phishing scam. Delete the email and do not engage with the sender.

Phishing Warning: Never provide your credit card information, passwords, or personal details to anyone over the phone claiming to be from Microsoft billing support.

Frequently Asked Questions

What should I do if I already clicked a link in the fake Microsoft invoice?

If you clicked a link and entered your login credentials, immediately go to account.microsoft.com and change your password. Enable two-factor authentication for added security. If you provided payment details, contact your bank or credit card provider right away to block any fraudulent charges.

Does Microsoft actually send invoices for $600?

While Microsoft does offer enterprise or bulk licensing that can reach this amount, a standard personal or family Microsoft 365 subscription costs significantly less (typically $70 to $100 per year). An unexpected $600 invoice sent to a personal email is highly indicative of a scam.

How can I report a phishing scam to Microsoft?

You can report a phishing email by forwarding it to phish@office365.microsoft.com or by using the 'Report Phishing' button built into Outlook and other major email clients.

Will I be charged if I just opened the scam email?

No, simply opening the email will not result in a charge. Scammers rely on you calling their fake support numbers or clicking malicious links to steal your payment information. As long as you did not interact with the contents or reply, your account is safe.
