Part 4 and closing chapter of the Conditional Access baseline series. The disciplined rollout cadence for moving all eight policies from Report-only to Enabled without incidents — pre-flight checks, Day 0 deployment, the seven-day review ritual, a worked What If scenario, a compact KQL triage set, the communication templates that make users feel informed instead of ambushed, and the specific failure patterns that only show up once you hit Enabled.

Part 3 of the Conditional Access baseline series. Every baseline policy walked end to end: the exact UI path, precise include/exclude scope, grant vs session choice with the real trade-offs, the common false positives and how to triage them in the sign-in logs, and the rollback pattern for each one — plus a Graph PowerShell appendix and two KQL queries that cover 80% of Report-only triage.

The opinionated Conditional Access baseline I deploy on every SMB Microsoft 365 tenant in 2026 — 8 policies split into a core and extended set, report-only rollout, break-glass done right, and the mistakes that lock admins out.
