What is the MS-900 Microsoft 365 Fundamentals exam?
The MS-900 Microsoft 365 Fundamentals exam is an entry level certification exam from Microsoft. It sits in the Cloud category at the Fundamental level, which means it does not assume prior technical experience. The exam checks whether you understand Microsoft 365 cloud services, the basics of security and compliance, how Microsoft prices its services, and the support options that come with them.
This exam suits business users, students, sales staff, help desk staff, and anyone starting out in cloud roles. You do not need to write code or manage servers to pass it. You do need a working understanding of what Microsoft 365 offers and how organizations use it day to day.
Passing the exam earns you the Microsoft Certified: Microsoft 365 Fundamentals credential. Many candidates use it as their first Microsoft certification before moving on to role based exams that go deeper into administration, security, or specific Microsoft 365 apps. It is also a common choice for people who want a recognized credential without committing months of study first.

What is on the MS-900 Microsoft 365 Fundamentals exam?
The exam covers four domains. Each one maps to a part of how organizations actually use Microsoft 365, from the core apps through to how the service is bought and supported.
| Domain | What it covers |
|---|---|
| Microsoft 365 Services | The core cloud services in Microsoft 365, including collaboration and productivity tools, and how they fit together. |
| Security & Compliance | The basics of identity, access, threat protection, and how Microsoft 365 helps organizations meet compliance needs. |
| Pricing | How Microsoft 365 licensing and billing works, and the options available to organizations of different sizes. |
| Support | The support options and service level commitments that come with Microsoft 365 subscriptions. |
Expect questions that describe a business scenario and ask you to pick the Microsoft 365 concept or service that fits. Very few questions ask you to recall a technical setting from memory. The exam is designed so that someone who understands Microsoft 365 conceptually, rather than someone who has memorized menus, can pass comfortably.
How hard is the MS-900 Microsoft 365 Fundamentals exam?
The MS-900 Microsoft 365 Fundamentals exam has 60 questions and gives you 60 minutes to complete them. You need a score of 700 (on 100 to 1000 scale) to pass.
As a Fundamental level exam, it is built to be approachable. It rewards broad understanding of Microsoft 365 rather than deep technical detail. That said, candidates who skip preparation still struggle, because the exam mixes questions across all four domains and expects you to know terms and concepts, not just guess from general computer knowledge.
If you already use Microsoft 365 at work, or you have read through the official skills outline, the exam should feel manageable. If Microsoft 365 is new to you, plan for a short period of focused study before you sit it. The time allowed is generous for the number of questions, so most candidates finish with time to review their answers rather than racing the clock.
How to prepare for the MS-900 Microsoft 365 Fundamentals exam
A simple study plan spread over a few weeks works well for most candidates. Adjust the pace to match how familiar you already are with Microsoft 365.
- Week 1: read the official MS-900 Microsoft 365 Fundamentals skills outline and note which topics are new to you.
- Week 2: study Microsoft 365 Services, focusing on the core apps and how they support collaboration.
- Week 3: study Security & Compliance, covering identity basics, threat protection, and compliance tools.
- Week 4: study Pricing and Support, covering licensing options, billing, and service level commitments.
- Week 5: work through free MS-900 practice questions to check your understanding across all four domains.
- Week 6: review any weak areas from your practice results, then book your exam once you feel ready.
Common mistakes people make
Some candidates treat MS-900 as a formality and walk in without reading the official skills outline. This backfires because the exam draws evenly from all four domains, and a gap in one area can cost you the pass.
Others focus only on the Microsoft 365 apps they use personally, such as Teams or Outlook, and skip Security & Compliance or Pricing entirely. These domains carry real weight on the exam, so they need real study time too.
A third mistake is leaving the voucher purchase until the last minute. Give yourself time to buy the voucher, receive it, and schedule a seat that suits your timetable, rather than rushing everything into one day. A fourth mistake is studying only from memory of the Microsoft 365 apps you personally use, without checking the official outline for topics you have never touched.
Is the MS-900 Microsoft 365 Fundamentals certification worth it?
For anyone who works with or around Microsoft 365, the MS-900 Microsoft 365 Fundamentals certification is a low cost way to prove that knowledge formally. It carries the Microsoft name, so employers and clients recognize it without explanation.
It also works well as a stepping stone. Many people who pass MS-900 go on to role based Microsoft exams that match their career direction, such as security, data, or app focused certifications. Cyber VK also sells vouchers for exams like AZ-204 Microsoft Azure Developer Associate, DP-203 Microsoft Azure Data Engineer Associate, PL-300 Microsoft Power BI Data Analyst Associate, MB-330 Microsoft Dynamics 365 Supply Chain Management Functional Consultant Associate, PL-200 Microsoft Dynamics 365 Customer Experience Analyst Associate, SC-100 Microsoft Cybersecurity Architect Expert, AB-900 Microsoft Copilot & Agentic AI Fundamentals, and MB-920 Microsoft Dynamics 365 Fundamentals ERP, so there is a clear next step once you have MS-900 in hand.
If you are weighing up whether to sit it, the cost is modest, the study load is light, and the certification stays useful on your resume for as long as Microsoft 365 remains part of the modern workplace. For a first step into Microsoft certification, it is hard to find a lower risk option.
