Microsoft will improve how Conditional Access policies are enforced in Microsoft Entra ID starting March 27, 2026. This change addresses a security loophole in which policies targeting all resources with specific exclusions could be bypassed in certain authentication scenarios. The rollout continues through June 2026 and forms part of Microsoft's Secure Future Initiative. Because these sign-ins will no longer bypass Conditional Access, users may now be required to complete MFA, meet device compliance requirements, or satisfy other configured Conditional Access controls, such as approved apps, app protection policies, or authentication strength, before accessing the resource.
