Microsoft Announces Strict DMARC Enforcement

Following Google and Yahoo’s similar announcement, more than a year ago, Microsoft has announced they will require properly configured DMARC, in order to send email to Microsoft’s consumer email domains (Outlook.com, Live.com, and Hotmail.com), beginning in May, 2025.

DMARC is an email authentication protocol that, together with SPF and DKIM, makes it easier to determine whether or not a given message is legitimately from the sender, and what to do if it isn’t. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing.
