Start 24-hour free trial →MS-900 has retired — AB-900 is the successor direction
Microsoft retired the MS-900 exam and its certification on March 31, 2026, as part of a broader certifications refresh (the Dynamics fundamentals MB-910 and MB-920 retired in the same wave). If you earned the credential before retirement, it stays on your Microsoft transcript permanently — Fundamentals certifications never expire.
New candidates can no longer schedule or sit MS-900. Microsoft has positioned the AI-focused AB-900 (Microsoft 365 Certified: Copilot and Agent Administration Fundamentals) as the entry-level Microsoft 365 successor; for a role-based admin path, the active MS-102 Microsoft 365 Administrator Expert carries more weight. Always confirm current status on Microsoft Learn.

About the Microsoft 365 Certified: Fundamentals certification
Microsoft 365 Fundamentals was Microsoft’s foundational credential for the Microsoft 365 cloud ecosystem. It validated a broad, conceptual understanding of how Microsoft 365 improves productivity and collaboration, secures data, and supports compliance — spanning the core apps (Word, Excel, Teams, SharePoint), Microsoft 365 Copilot, endpoint management with Intune, security with Microsoft Entra and Defender, compliance with Microsoft Purview, and the licensing and support model. It was deliberately non-technical: no coding or hands-on administration was required, which made it popular with business users, IT support staff, and career changers.
MS-900 and its certification retired on March 31, 2026. Unlike the Dynamics fundamentals, MS-900 has an announced successor: the AI-focused AB-900 (Copilot and Agent Administration Fundamentals) is positioned as the entry-level Microsoft 365 path going forward. The concepts on this page remain a solid grounding in the Microsoft 365 ecosystem, and the practice questions are still useful for that. For a role-based technical path, the active MS-102 Microsoft 365 Administrator Expert is where administrators go next, and SC-900 Security, Compliance, and Identity Fundamentals remains an active fundamentals option covering the security topics MS-900 introduced.
Every PowerKram practice question maps to one of the four MS-900 skill areas and links to the specific Microsoft Learn page it was derived from, so your weak spots become a focused reading list rather than a guess.
MS-900 skill areas and weights
Four skill areas, with Microsoft 365 apps and services by far the heaviest at 45–50% — nearly half the exam. Microsoft published each area as a weighting range rather than an exact percentage; the ranges below are reproduced as Microsoft stated them in the final MS-900 edition.
Productivity apps (Word, Excel, PowerPoint, OneNote) and Microsoft 365 Copilot; collaboration (Teams, SharePoint, OneDrive, Exchange, Viva); endpoint and device management (Intune, Windows Autopilot, Windows 365 vs Azure Virtual Desktop); and Microsoft 365 administration and reporting.
Identity and access with Microsoft Entra ID (MFA, SSPR, conditional access); threat protection with Microsoft Defender XDR and Secure Score; and trust, privacy, risk, and compliance with the Zero Trust model, Microsoft Purview, and Priva.
Pricing and billing models (enterprise agreements, cloud solution providers, direct billing); base versus add-on licensing and license management; and support options including how to raise a request, SLAs and service credits, and checking service health.
Cloud service types (SaaS, PaaS, IaaS) and their use cases; the difference between Office 365 and Microsoft 365; public, private, and hybrid cloud models; and the concept of hybrid and flexible work.
Source: Microsoft Learn — MS-900 study guide (skills measured, as of April 30, 2025). Microsoft published weightings as ranges; apps and services was by far the heaviest area.
Who MS-900 was for
Microsoft 365 Fundamentals suited anyone needing foundational literacy in the Microsoft 365 cloud, technical or not:
- Business users and stakeholders involved in Microsoft 365 procurement, rollout, or day-to-day use who need the vocabulary of the platform.
- IT support and help-desk staff fielding Microsoft 365 questions who want a structured map of the ecosystem.
- Career changers and students entering IT and cloud roles.
- Sales, procurement, and partner staff who evaluate or recommend Microsoft 365 licensing and solutions.
There were no prerequisites. Because MS-900 has retired, new candidates should look at the successor direction — AB-900 (Copilot and Agent Administration Fundamentals) — or, for a role-based technical path, the active MS-102 Microsoft 365 Administrator Expert. The active SC-900 Security, Compliance, and Identity Fundamentals and AZ-900 Azure Fundamentals are natural fundamentals companions.

An organization subscribes to Microsoft 365 and accesses fully managed applications like Exchange Online and Teams over the internet, without managing any servers or infrastructure.
Which cloud service model does this describe?
- Infrastructure as a service (IaaS)
- Platform as a service (PaaS)
- Software as a service (SaaS)
- On-premises hosting
Show answer & explanation
Correct: C — Software as a service (SaaS). Microsoft 365 is delivered as SaaS: Microsoft hosts and fully manages the applications, and customers consume them over the internet without managing servers or infrastructure — exactly as described.
Why not the others: IaaS (A) provides virtual machines and networking that the customer manages; PaaS (B) provides a managed platform for building apps; on-premises (D) means the customer runs everything themselves. None matches a fully managed, ready-to-use app.

Which Microsoft 365 service is designed for this?
- Microsoft Purview
- Microsoft Teams
- Microsoft Intune
- Microsoft Entra ID
Show answer & explanation
Correct: B — Microsoft Teams. Teams is the hub for meetings, chat, file collaboration, and calling (Teams Phone) in Microsoft 365 — exactly the collaboration hub described.
Why not the others: Purview (A) is compliance and governance; Intune (C) manages devices; Entra ID (D) manages identity and access. None is the meetings-and-collaboration hub.
Source: Microsoft Learn — Microsoft Teams overview →An organization wants an AI assistant that works across Word, Excel, PowerPoint, Outlook, and Teams to draft content, summarize, and analyze data using the organization’s own Microsoft 365 data.
Which capability is this?
- Windows Autopilot
- Microsoft 365 Copilot
- Microsoft Secure Score
- Windows 365
Show answer & explanation
Correct: B — Microsoft 365 Copilot. Copilot is the generative-AI assistant embedded across the Microsoft 365 apps, grounded in the organization’s Microsoft 365 data — exactly the cross-app AI described. It was a major addition to the April 2025 MS-900 blueprint.
Why not the others: Windows Autopilot (A) provisions devices; Secure Score (C) measures security posture; Windows 365 (D) is a Cloud PC service. None is the cross-app AI assistant.

Show answer & explanation
Correct: A — Microsoft OneDrive. OneDrive provides individual cloud file storage with sync and sharing across devices; SharePoint, by contrast, is for team and site content. OneDrive matches the per-employee file storage described.
Why not the others: Defender XDR (B) is threat protection; Entra ID (C) is identity; Priva (D) is privacy management. None is personal file storage.
Source: Microsoft Learn — Microsoft 365 documentation →A security team wants to require a second verification factor — such as an approval in an authenticator app — when users sign in, to reduce the risk of compromised passwords.
Which Microsoft Entra ID capability provides this?
- Data loss prevention (DLP)
- Multi-factor authentication (MFA)
- Sensitivity labels
- eDiscovery
Show answer & explanation
Correct: B — multi-factor authentication (MFA). MFA requires a second verification factor beyond the password — such as an authenticator-app approval — and is a core Microsoft Entra ID identity-protection capability, exactly as described.
Why not the others: DLP (A) and sensitivity labels (C) are Microsoft Purview information-protection features; eDiscovery (D) is a compliance/investigation tool. None is a sign-in verification factor.
Source: Microsoft Learn — What is Microsoft Entra ID? → Further reading: PowerKram — SC-900 Security, Compliance & Identity Fundamentals →An organization adopts a security strategy that assumes breach, verifies every request explicitly, and grants only least-privilege access rather than trusting anything inside the network by default.
Which security model is this?
- The Zero Trust model
- The shared responsibility model
- The waterfall model
- The perimeter (castle-and-moat) model
Show answer & explanation
Correct: A — the Zero Trust model. Zero Trust assumes breach, verifies explicitly, and enforces least-privilege access rather than trusting anything by default — exactly the strategy described. It is part of the MS-900 trust and compliance area.
Why not the others: the shared responsibility model (B) divides security duties between provider and customer; waterfall (C) is a project methodology; the perimeter model (D) is the older “trust the internal network” approach Zero Trust replaces.
Source: Microsoft Learn — Zero Trust model →A compliance team needs to classify sensitive documents automatically and prevent confidential data from being shared outside the organization.
Which Microsoft solution provides sensitivity labels and data loss prevention?
- Microsoft Intune
- Microsoft Teams
- Microsoft Purview

Deep dive: MS-900 format, the retirement, study path, and where the Microsoft 365 track leads now
Exam format and scoring
MS-900 was a fundamentals exam: roughly 40 to 60 questions in about 60 minutes, with a passing score of 700 out of 1000 (scaled). Question formats included multiple choice, multiple response, drag-and-drop, and short scenario-based items. There was no penalty for wrong answers, and the exam focused on concepts and service-to-scenario matching rather than hands-on configuration. See the MS-102 Administrator Expert path →
The retirement — what it means
MS-900 retired on March 31, 2026, as part of Microsoft’s certifications refresh toward AI-focused and self-paced learning. Its date was originally December 31, 2025 (alongside the Dynamics fundamentals MB-910 and MB-920) but was pushed to March 31, 2026, then held. Unlike the Dynamics pair, MS-900 has an announced successor direction: the AI-focused AB-900 (Copilot and Agent Administration Fundamentals). If you earned MS-900 before retirement it remains on your transcript permanently; if you are starting now, consider AB-900 or a role-based path such as MS-102.

What the April 2025 update changed
The final MS-900 edition (skills measured as of April 30, 2025) modernized the apps-and-services and security areas: it added Microsoft 365 Copilot and Copilot Chat, the Microsoft Viva apps, and Granular Delegated Admin Privileges (GDAP), and it removed the older Microsoft 365 lifecycle topic. Anyone studying from pre-2025 material would have hit gaps on Copilot, Viva, Defender XDR, and Zero Trust content. This AI-forward shift is exactly why AB-900 — a Copilot-centric fundamentals exam — became the successor. See the SC-900 Security fundamentals path →
Realistic study path (for review)
MS-900 typically took one to three weeks. The concepts still hold value: be able to match a scenario to the right service — Teams or SharePoint (collaboration), Intune (devices), Entra ID (identity), Defender (threats), Purview (compliance) — and understand the licensing and support model. Apps and services was by far the heaviest area at 45–50%, so most study time belonged there. See the AZ-900 Azure Fundamentals path →
Cost and delivery (historical)
MS-900 cost $99 USD (regional pricing varied) and was delivered at a Pearson VUE test center or online with a proctor. Microsoft frequently offered free exam vouchers through Virtual Training Day events. These details are historical, since the exam can no longer be scheduled.

Career outlook for Microsoft 365 skills
Microsoft 365 fundamentals remain valuable for help-desk, IT-support, and administrator roles, even though the fundamentals exam has retired. The current path runs through the AB-900 successor and role-based exams like MS-102 (Administrator Expert), with the security fundamentals SC-900 pairing naturally for compliance-focused roles.
