The AB-650: Administering Microsoft 365 and AI Services exam is the new Microsoft certification exam for administrators who manage Microsoft 365 tenants, workloads, Microsoft 365 Copilot, agents, and connected AI services. As Microsoft shifts Microsoft 365 administration toward AI-powered productivity, governance, data protection, and agent management, AB-650 has become an important replacement path for candidates preparing beyond MS-102, which is scheduled to retire on October 31, 2026. To help you pass the exam easily, the most valid AB-650 Prep Guide with Practice Test Questions from PassQuestion covers Microsoft 365 tenant administration, Microsoft Entra ID, Defender for Office 365, Microsoft Purview, Microsoft 365 Copilot, Agent 365, Copilot Control System, and AI service monitoring.

What Is the AB-650: Administering Microsoft 365 and AI Services Exam?

The AB-650 exam is associated with the Microsoft 365 Certified: AI Services Administrator Associate certification. Microsoft describes this role as responsible for configuring, managing, securing, and governing Microsoft 365 tenants, workloads, and AI services, including Microsoft 365 Copilot, agents, and connected AI capabilities. Candidates also support secure, compliant, and scalable productivity by governing data access, protecting information, and helping users and agents collaborate effectively.

This exam is currently listed as a beta exam. Candidates should have experience with Microsoft 365 workloads and Microsoft Entra ID, understand Defender XDR capabilities, and be familiar with Microsoft Graph PowerShell.

Transition from MS-102 to AB-650

The transition from MS-102: Microsoft 365 Administrator to AB-650: Administering Microsoft 365 and AI Services reflects Microsoft's move from traditional Microsoft 365 administration toward AI-first administration. MS-102 focused on Microsoft 365 tenant management, Microsoft Entra identity and access, Microsoft Defender XDR, and Microsoft Purview compliance. Microsoft's retirement page lists MS-102 as scheduled to retire on October 31, 2026, while the Microsoft 365 Administrator Expert certification page also warns that the certification and related exam will retire in October 2026.

AB-650 keeps many Microsoft 365 administration foundations, such as tenant management, identity, authentication, Defender, and Purview, but expands the role into modern AI service administration. It adds stronger focus on Microsoft 365 Copilot readiness, AI service licensing, Copilot Search, agent identities, agent registry management, Agent 365 governance, Copilot Control System monitoring, AI cost tracking, and AI activity security. For candidates, this means preparation should no longer focus only on Microsoft 365 administration; it should also include how AI services and agents access, use, protect, and expose enterprise data.
