The aim of these mail service providers was simple - to build a cyber-resilient digital ecosystem.

The aim of these mail service providers was simple - to build a cyber-resilient digital ecosystem. Recently, another major ESP - Microsoft, jumped the bandwagon and announced that it will now take even more proactive steps to make the inboxes more safe and secure. _The three core email authentication standards - SPF ([RFC 7208](https://datatracker.ietf.org/doc/html/rfc7208)), DKIM ([RFC 6376](https://datatracker.ietf.org/doc/html/rfc6376)), and DMARC ([RFC 7489](https://datatracker.ietf.org/doc/html/rfc7489)) - work together to verify that an email genuinely originates from the domain it claims to represent. Since February 2024, Google and Yahoo require all three for bulk senders._ Let us take a look at Microsoft’s new policy updates and what they mean for your business. ## What is Microsoft’s New Strategic Move All About? [Email-based cyberattacks](https://www.helpnetsecurity.com/2023/07/10/evolving-cyberattack-landscape/) like phishing, spoofing, and ransomware are at an all-time high. What’s worse is that these attacks spare no one, whether it is a big organization or a small business; the moment the attackers spot a lucrative opportunity, they shoot their shot. To tackle this plague and create a safe environment for its users, Microsoft has decided to follow the same route as its counterparts, [Google and Yahoo](/blog/ushering-a-new-era-of-security-google-and-yahoos-take-on-email-authentication/), and implement stronger email authentication practices. This move shows their commitment to making email a secure communication channel and improving [email deliverability](/blog/how-does-spf-help-marketers-in-improving-email-deliverability/). ![phishing attack](https://media.mailhop.org/autospf/images/2024/06/how-to-create-spf-record-2.jpg) Here’s what you should know about the new update: ### Joining Forces with Industry Leaders By aligning with the latest email-sending policies laid out by Google and Yahoo in October 2023, Microsoft strives for near-global adoption of email authentication requirements for both consumer and [enterprise mailboxes](https://www.terra-master.com/global/enterprise%5Fmailbox%5Fsolution#:~:text=Enterprise%20mailbox%20is%20a%20mailbox,daily%20business%20management%20and%20activities.). Although we do not have a deadline yet, Microsoft has indicated that it is a matter of ‘when’ and not ‘if,’ making it abundantly clear that these new policies are imminent. That is to say, businesses sending consumer emails will need to comply with these new standards. ### Mandatory Implementation of Email Authentication Protocols In this policy update, Microsoft has further tightened its requirements to ensure enhanced [email security](/). _For an email to pass through, it is now a requirement for the sender organization to implement [Sender Policy Framework](/blog/what-is-spf-email-a-guide-to-sender-validation-technology/) (SPF) and DomainKeys Identified Mail ([DKIM](/10-reasons-for-regular-spf-record-checks-in-cybersecurity/dkim-record-check/)), along with Domain-based Message Authentication, Reporting, and Conformance (DMARC) for their domain_. This is, perhaps, one of the most significant updates of them all. By simply authenticating sender domains with these protocols, Microsoft aims to significantly reduce the risk of email-based attacks, protecting both businesses and their consumers from potential [cyber threats](https://www.bbc.com/news/technology-67221117). ### Stricter DMARC Enforcement with p=quarantine or p=reject Microsoft recognizes that simply asking organizations to authenticate their domains with DMARC won’t suffice, especially in this [ever-evolving threat landscape](https://cybermagazine.com/articles/the-rapidly-evolving-threat-landscape-of-2024). This is why the ESP is now encouraging senders to move towards policies like [p=quarantine and p=reject](https://dmarcreport.com/blog/switch-from-pquarantine-to-preject-in-dmarc/). _These policies ensure that emails failing DMARC checks are either sent to the spam folders (quarantine) or blocked completely (reject)_. While Microsoft hasn’t provided a specific timeline, they have indicated that this enforcement is inevitable. ### Regular Maintenance of DNS Records From directing your emails to the correct destinations to verifying the legitimacy of your email domains, DNS does it all! [Considering DNS](https://dnsmadeeasy.com/post/the-interplay-between-dns-and-email-an-essential-guide-for-dns-professionals) is such an integral aspect of your email ecosystem, it is crucial to keep it up-to-date and the new update of Microsoft expects you to do the same. To this end, make sure that you have valid DNS records and that you follow the recommended configurations. ### Maintain a Low Spam Rate Microsoft wants you to maintain a [good sender reputation](https://www.moengage.com/blog/reasons-you-should-protect-your-email-sender-reputation-and-tips-to-help-you-achieve-this/) among your clients, which is why it has introduced measures to help you keep your [spam rate](https://emailmastery.org/email-marketing-glossary/spam-rate/) low. _To achieve this, you have to send only relevant and valuable content and regularly clean your email list to remove inactive or unengaged recipients._ ![email authentication](https://media.mailhop.org/autospf/images/2024/06/spf-flattening-7259.jpg) ## How Will It Impact Your Business? If your organization relies on email to communicate with your clients and potential customers, Microsoft’s new update is for you! As you know, simply sending out emails to your audience won’t do any good to your business. _It is only when your emails reach the right audience and are perceived as trustworthy that they can be effective_. To make that happen and prevent your emails from being marked as spam, you must deploy DMARC and other email authentication protocols. Moreover, by doing this, you can protect your brand from being spoofed or [impersonated by malicious actors](https://thehackernews.com/2024/05/fake-antivirus-websites-deliver-malware.html). After Google and Yahoo, now that Microsoft has also adopted these stringent [email authentication](/spf-too-many-dns-lookups/spf-lookup/) measures, email communication is all set to become more secure!
