What's New in 2026
AB-900 is part of Microsoft's new AI Business Solutions certification track launched in 2026 — the most significant Microsoft certification overhaul in a decade. It replaces MS-900 for IT administrators managing Copilot environments.
Course Overview
AB-900 is Microsoft's foundational certification for IT administrators responsible for deploying, governing, and securing Microsoft 365 Copilot in their organisation. As enterprises roll out Copilot at scale, someone needs to own the governance, compliance, and security of AI in the Microsoft 365 environment — AB-900 certifies that person. This 1-day instructor-led course covers Copilot deployment and configuration, Microsoft Purview governance, agent management in Copilot Studio, security controls, and responsible AI administration.
