For Office 365 users, implementing DMARC (Domain-based Message Authentication, Reporting, and Conformance) is crucial to enhance email security. Setting up DMARC involves configuring SPF and DKIM, creating a DMARC DNS record, specifying a policy for handling failed authentications, monitoring reports, and gradually enforcing stricter policies. This helps prevent email spoofing, phishing attacks, and safeguards your organization's email integrity, making DMARC an essential protocol for Office 365 users.
