If you receive an e-mail message that tells you that you have won the Microsoft Lottery or any lottery, delete the message. There is no Microsoft Lottery. There are other lotteries, of course, but if you don’t remember entering them, then the e-mail message is probably a scam.
This type of scam is designed to convince you to send cyber criminals money or to hand over your personal information in advance of receiving your prize. That’s why this scam is sometimes called Advance Fee Fraud.
For more information about Advance Fee Fraud or how Microsoft is working with Western Union and The United States Postal Inspection Service to help you avoid this scam, see Avoid Advance Fee Fraud and other lottery scams.
