Currently when email is sent to Microsoft email accounts, if the email fails DMARC the policy is to quarantine the email message. E.g. place the failed email into your junk folder.
Once this rollout is complete, the DMARC policy across Microsoft’s consumer and enterprise services will have been updated from quarantine to reject. Therefore, should an email fail Microsoft’s DMARC authentication, then the email will be rejected and won’t land in the receiver’s inbox at all, with the sender notified that the email was not delivered.
By implementing this DMARC reject policy, Microsoft aims to help protect its users from spam, phishing, and other email-based fraud by ensuring that only legitimate email messages are delivered to their inboxes.
This means that any organisation that does not have their DMARC record configured correctly for all its email domains and senders, their email will no longer be received by businesses or consumers.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a protocol used for authenticating email domains. DMARC has been created to give domain owners the ability to protect their domains from unauthorised use or abuse. DMARC is used to help combat email phishing and other types of email fraud.
Additionally, enabling a DMARC record can help to improve domain owners’ sender reputation and email deliverability.
