Solution 1Recommended

Identify and Safely Handle the Phishing Email

Take immediate precautions to protect your personal information and device from the malicious phishing attempt.

Fake invoice scams rely on creating a false sense of urgency. The scammers want you to call the fake customer support number provided in the email to dispute the charge, at which point they will attempt to steal your financial information or gain remote access to your computer.

Inspect the email sender

Check the actual sender's email address by expanding the email header details. Phishing emails usually come from non-Microsoft domains (such as generic Gmail, Yahoo, or random character domains) instead of official @microsoft.com addresses.

Avoid interaction

Do not reply to the email, click any hyperlinked text, open attached PDF or Word invoices, or call the provided customer service phone numbers.

Report and delete

Mark the email as 'Phishing' or 'Spam' using your email provider's built-in reporting tools, then delete the message permanently from your inbox.

Scan your device

Run a full system scan using Windows Defender or another reputable security software to ensure no background malware was accidentally downloaded.

Do Not Call: Microsoft will never send an unsolicited email demanding you call a specific phone number to cancel an order.

Solution 2

Verify Your Subscriptions Officially

Confirm your account status by logging directly into the official Microsoft portal without using any links from the suspicious email.

Frequently Asked Questions

How can I tell if an email from Microsoft is legitimate?

Disconnect your device from the internet immediately to prevent further data transmission. Run a full scan using your antivirus software. Once verified clean, use a different, secure device to change your Microsoft account password and enable two-factor authentication.

Where can I report a fake Microsoft 365 invoice email?

You can report the scam by forwarding the suspicious email as an attachment to phishing@microsoft.com. Additionally, if you use Outlook, you can use the 'Report Message' button on the ribbon to submit the email directly to Microsoft's security team.
