Microsoft 365 Fundamentals MS-900 Legacy Practice Exam
Microsoft retired the MS-900 Microsoft 365 Fundamentals exam on March 31, 2026. Fundamentals certifications do not expire, and a credential you already earned stays on your Microsoft Learn transcript. The closest current Microsoft 365 fundamentals credential is AB-900, Copilot and Agent Administration Fundamentals, but it is not a like-for-like replacement because it focuses on administering Copilot and agents.
MS-900 allowed 45 minutes and needed 700 to pass. Its last skills outline, dated April 30, 2025, weighted Describe cloud concepts at 5-10%, Describe Microsoft 365 apps and services at 45-50%, Describe security, compliance, privacy, and trust at 25-30%, and Describe pricing, licensing, and support at 10-15%.
These 1,201 questions still work as a broad tour of Microsoft 365 services, security, and licensing. If you are choosing a current exam, compare the AB-900 page with AB-730 for non-administrators, AB-731 for AI transformation leaders, and SC-900 for security fundamentals.

Exam Overview
Microsoft retired the MS-900 Microsoft 365 Fundamentals exam on March 31, 2026. Fundamentals certifications do not expire, and a credential you already earned stays on your Microsoft Learn transcript.
The last skills outline, dated April 30, 2025, weighted cloud concepts at 5-10%, Microsoft 365 apps and services at 45-50%, security, compliance, privacy, and trust at 25-30%, and pricing, licensing, and support at 10-15%. The closest current credential is AB-900, Copilot and Agent Administration Fundamentals, which focuses on administering Copilot and agents.
Who Should Take This Exam
MS-900 is designed for individuals seeking to demonstrate foundational cloud knowledge without prior deep technical expertise. Ideal candidates include IT support specialists, helpdesk technicians, junior cloud administrators, business analysts, and project coordinators who work alongside Microsoft 365 environments and want to formalize their understanding. It also suits students and career changers entering the IT field, as well as sales professionals, procurement managers, and non-technical stakeholders who need fluency in M365 capabilities to guide organizational decisions or engage with enterprise clients.
This certification serves as an on-ramp to Microsoft's broader role-based certification paths. Professionals aiming for credentials such as Microsoft 365 Administrator Expert (MS-102), Modern Desktop Administrator Associate, or Security, Compliance, and Identity Fundamentals often use MS-900 to build conceptual grounding before advancing to more technical exams.
Prerequisites
Microsoft lists no formal prerequisites for MS-900. The exam is intentionally accessible to candidates who are new to Microsoft 365 or cloud services in general. No hands-on IT experience is required, and the exam can be taken without prior Microsoft certifications.
That said, candidates benefit most from having a basic familiarity with general IT concepts, such as the difference between on-premises and cloud environments, and some exposure to everyday Microsoft 365 tools like Outlook, Teams, or Word. Those completely new to cloud computing are advised to complete the free Microsoft Learn learning paths covering cloud concepts and Microsoft 365 services before scheduling the exam, as even foundational fluency with SaaS, IaaS, and PaaS distinctions is tested.
Exam Format
MS-900 allowed 45 minutes and required 700 to pass. It can no longer be scheduled.

Study Tips
- Follow the official Microsoft Learn learning paths mapped to MS-900 objectives — these free, self-paced modules are structured around the exact exam domains and are the most authoritative preparation resource available.
- Take the free official Practice Assessment on Microsoft Learn (Assessment ID 50) before and after your study period. It mirrors the actual exam's question style and difficulty and highlights specific knowledge gaps to address.
- Use the MS-900 Study Guide on Microsoft Learn to track which skills are covered by the April 30, 2025 version of the exam — pay attention to recently added topics like Microsoft 365 Copilot capabilities, Microsoft Priva, and the Copilot dashboard, as these reflect the latest update.
- Launch the Microsoft Exam Sandbox (available from the exam page) to experience the interactive question types — drag-and-drop and scenario-based items require familiarity with the interface to avoid time loss on exam day.
- Focus your heaviest study time on the 'Describe Microsoft 365 apps and services' domain (45–50%) and 'Describe security, compliance, privacy, and trust' domain (25–30%), as together they represent up to 80% of the scored content.
- For the security domain, map each Defender product (Defender for Endpoint, Defender for Office 365, Defender for Identity, Defender for Cloud Apps) to its specific threat scenario — Microsoft frequently tests candidates' ability to distinguish which tool addresses which type of threat.
- Review the Microsoft 365 Tech Community and the Exam Readiness Zone video series on Microsoft Learn for reinforcement of complex topics like Conditional Access, Microsoft Purview compliance tools, and licensing tier differences.
