MS-102 Retires November 30, 2026: Transition Guide

What This Exam Validates

MS-102, Microsoft 365 Administrator, remains available only until 2026-11-30. Its published domains cover Deploy and manage a Microsoft 365 tenant, Implement and manage Microsoft Entra identity and access, Manage security and threats by using Microsoft Defender XDR, Manage compliance by using Microsoft Purview. MS-102 describes the integrating-hub role rather than a single workload specialty. The strongest preparation follows a change across tenant configuration, identity synchronization, Conditional Access, Defender XDR, endpoint protection, and Purview so that security and compliance effects are visible end to end. Microsoft does not name a direct replacement in the reviewed official sources. This page keeps the dated blueprint useful while separating verified lifecycle facts from recommendations.

Who Should Take This Exam

The original audience was Microsoft 365 administrators who coordinate tenant, identity, security, endpoint, collaboration, and compliance work across cloud and hybrid environments. Current candidates should use the cutoff and active Microsoft catalog to decide whether MS-102 still fits; the absence of a named replacement is not evidence that a similarly named exam is equivalent.

Skills You Should Be Ready to Demonstrate

• Deploy, license, monitor, and delegate administration in a Microsoft 365 tenant
• Operate synchronized identity, authentication methods, Identity Protection, and Conditional Access
• Investigate and respond across Defender XDR, Defender for Office 365, Endpoint, and Cloud Apps
• Implement Purview information protection, retention, data loss prevention, and alert response

How to Prepare Before Retirement

Use a test tenant to build operational runbooks for onboarding, role delegation, identity synchronization, secure access, threat investigation, endpoint response, and information protection. For each task, capture prerequisites, least-privilege roles, the correct admin surface, verification evidence, and a recovery path. Start with the dated Microsoft guide, map each objective to a task, decision, observable result, and failure mode, and use domain ranges to balance coverage rather than predict question counts. Keep notes labeled with the guide date so future product or blueprint changes do not silently contaminate the plan.

Domain Study Guidance

Deploy and manage a Microsoft 365 tenant: Study Guidance

Domain 1, Deploy and manage a Microsoft 365 tenant, organizes related decisions rather than isolated product facts. The current outline includes Implement and manage Microsoft Entra identity and access; Manage users and groups. Practice by connecting the configuration or recommendation to prerequisites, downstream effects, evidence of success, and a safe correction when the expected result is not observed.

• Turn every Deploy and manage a Microsoft 365 tenant objective into a concrete task or decision you can explain
• Record the prerequisite, implementation choice, verification signal, and failure mode
• Mix this domain with adjacent domains so dependencies remain visible

Implement and manage Microsoft Entra identity and access: Study Guidance

Domain 2, Implement and manage Microsoft Entra identity and access, organizes related decisions rather than isolated product facts. The current outline includes Implement and manage identity synchronization with Microsoft Entra tenant; Implement and manage authentication; Implement and manage secure access. Practice by connecting the configuration or recommendation to prerequisites, downstream effects, evidence of success, and a safe correction when the expected result is not observed.

• Turn every Implement and manage Microsoft Entra identity and access objective into a concrete task or decision you can explain
• Record the prerequisite, implementation choice, verification signal, and failure mode
• Mix this domain with adjacent domains so dependencies remain visible

Manage security and threats by using Microsoft Defender XDR: Study Guidance

Domain 3, Manage security and threats by using Microsoft Defender XDR, organizes related decisions rather than isolated product facts. The current outline includes Review and respond to security reports and alerts generated by Microsoft Defender XDR; Implement and manage email and collaboration protection by using Microsoft Defender for Office 365; Implement and manage endpoint protection by using Microsoft Defender for Endpoint. Practice by connecting the configuration or recommendation to prerequisites, downstream effects, evidence of success, and a safe correction when the expected result is not observed.

• Turn every Manage security and threats by using Microsoft Defender XDR objective into a concrete task or decision you can explain
• Record the prerequisite, implementation choice, verification signal, and failure mode
• Mix this domain with adjacent domains so dependencies remain visible

Manage compliance by using Microsoft Purview: Study Guidance

Domain 4, Manage compliance by using Microsoft Purview, organizes related decisions rather than isolated product facts. The current outline includes Implement Microsoft Purview information protection and data lifecycle management; Implement Microsoft Purview data loss prevention (DLP). Practice by connecting the configuration or recommendation to prerequisites, downstream effects, evidence of success, and a safe correction when the expected result is not observed.

• Turn every Manage compliance by using Microsoft Purview objective into a concrete task or decision you can explain
• Record the prerequisite, implementation choice, verification signal, and failure mode
• Mix this domain with adjacent domains so dependencies remain visible

Exam-Day Guidance

Microsoft lists 2026-11-30 as the retirement date. Verify the official page immediately before booking, allow time for identity and accommodation requirements, and do not assume a retake can be scheduled after the cutoff.
