"For months, scammers have been taking advantage of a loophole that allows them to send spammy emails from an internal Microsoft email address typically used for sending legitimate account alerts," TechCrunch reports:

[The scammers] have been able to set up new Microsoft accounts as if they are new customers and use that access to send out emails purportedly from the tech giant, potentially tricking people into thinking these emails are genuine...

Last week, I received several, similarly structured emails containing subject lines and web links to scammy sites from Microsoft across different email accounts. These crudely made emails were sent from [email protected], an email account that Microsoft uses to send important notifications to users, such as two-factor authentication codes and other critical alerts about their online account. Some of these emails' subject lines resembled official emails that would alert users to fraudulent transactions, while other emails claimed to have a private message waiting for the recipient at a web address mentioned in the email body.

In a social post on Tuesday, anti-spam nonprofit The Spamhaus Project said it had also seen Microsoft's account notification email address being abused to send spam and that the activity dated back "several months."

A PR representative told TechCrunch that Microsoft was "actively investigating" and "taking action against these phishing reports to help keep customers protected," with measures that include "removing accounts that violate our Terms of Use" and "further strengthening our detection and blocking mechanisms."

TechCrunch suggests the issue may not be limited to Microsoft. "Other users commenting on social media say that other companies' email addresses are also being used to send out spam."
