Hello Matt Bainbridge, Thank you for posting your query on Microsoft Q&A platform.

What you’re describing closely aligns with a known scam pattern involving Azure alert emails.

In these cases, attackers first gain access to an Azure subscription and then deliberately configure alert rules to send notifications to external email addresses (such as yours). They subsequently trigger those alerts. While the emails are technically generated by Azure, the alert message content itself is authored by the attackers.

These emails typically include alarming language such as:

• references to a “Fraud Prevention System” or “Windows Defender,”
• warnings about large, suspicious charges,
• threats of account suspension, and
• a so‑called “Fraud Resolution” or “Support Hotline” phone number.

The objective is to pressure recipients into calling that number, where the scam continues.

Important guidance:

• Do not call any phone number mentioned in the email.
• Do not click any links included in the message.
• Simply delete the email.

It’s worth noting that these messages can appear convincing because they are sent from legitimate Microsoft email infrastructure. However, Microsoft does not include phone numbers or urgent call‑to‑action language like this in genuine Azure alert notifications.

Hi Matt,

Recently (past few weeks) there have been malicious Azure Monitor Alert messages going out and what you received match the pattern.

DO NOT call any phone number(s) in the email messages.

It appears what is happening is bad actors get access to an Azure subscription, set up Alerts with potential victim's email address (your email) set as recipient, then trigger alert. In the text of the alert they mention things like Fraud Prevention System, Windows Defender, some substantial $ amount, potentially unauthorized charge, account suspension, Fraud Resolution Hotline, etc., and their goal is for you to call a phone number.

DO NOT call any phone number in the email. They want you to call them so they can scam you.

Currently there isn't a good way to make them stop. You could create an email rule to move them to separate folder. I don't recommend blocking them permanently because they are from a real Microsoft email address. The text of the alert is written by the scammers.
