At least one Conditional Access policy is configured to block legacy authentication for Exchange ActiveSync
Why This Matters
Legacy authentication protocols, such as Exchange ActiveSync, do not support modern security features like multifactor authentication (MFA). Attackers commonly exploit these protocols to bypass Conditional Access policies and gain unauthorized access to mailboxes. Without a policy blocking legacy authentication for Exchange ActiveSync, your organization remains vulnerable to credential theft and data breaches.
