Entra Conditional Access Policy Blocking Legitimate User
Use this guide when Entra Conditional Access blocks a legitimate sign-in and the user needs a clear remediation path. It helps you confirm the failing policy condition first, then choose the least disruptive enterprise-safe fix.
Estimated time
20-40 min
Overview
Conditional Access is supposed to be strict, but from the user side it often looks arbitrary when a trusted person is suddenly blocked. The fastest way to make progress is to identify exactly which signal caused the policy decision: device compliance, location, MFA requirement, app scope, or session risk.
