MS-900 Certification Guide 2026: How to Pass Microsoft 365 Fundamentals Before It Retires

If you’re reading this, chances are you’ve heard the news.
MS-900 is retiring on March 31, 2026. ⏰
And suddenly, what felt optional now feels urgent.
I still remember the morning I sat my own MS-900 exam. Coffee in hand. Slight nerves. Eight years ago, Microsoft 365 wasn’t what it is today — no Copilot, no Defender XDR integration at this scale. But the core idea was the same: understand the ecosystem.
I passed on my first attempt. Since then? I’ve helped over 1,200 students pass MS-900 certification — IT admins, consultants, career switchers, project managers.
And here’s the truth:
This exam is still absolutely worth it in 2026 — but only if you approach it strategically.
So let’s talk. No fluff. No corporate buzzwords. Just real guidance on how to pass MS-900 confidently before it retires.
Why the Retirement Actually Makes MS-900 More Valuable (Not Less)
The official retirement date is confirmed on Microsoft’s certification retirement page (March 31, 2026). 📅
When an exam retires, two things happen:
- Employers rush to validate baseline knowledge.
- Candidates delay — and miss the window.
If you earn MS-900 certification before retirement, you’ll still hold the credential permanently on your transcript. It doesn’t disappear.
And for many roles, especially:
- Junior IT admins
- Help desk transitioning to cloud
- Sales engineers
- Project managers managing M365 rollouts
- Career switchers entering tech
…it’s still one of the cleanest entry points into Microsoft 365 Fundamentals.
Who Should Take MS-900 in 2026 (And Who Should Skip It)
Let’s be honest.
✅ You Should Take MS-900 If:
- You’re new to Microsoft 365
- You work around M365 but lack structured knowledge
- You want a foundational cert before MS-102 or SC-900
- You’re transitioning into cloud roles
❌ You Might Skip It If:
- You already hold MS-102 or equivalent experience
- You architect Microsoft 365 at enterprise scale
- You manage complex licensing daily
For most beginners, MS-900 still builds a mental map of the ecosystem. That map matters.

What Changed in the April 30, 2025 Skills Update
This is where many candidates fall behind.
Microsoft updated the skills measured on April 30, 2025. And yes — Copilot and Zero Trust now matter more.
Here’s the current breakdown:
| Domain | Weight |
|---|---|
| Cloud Concepts | 5–10% |
| Microsoft 365 Apps & Services | 45–50% |
| Security, Compliance, Privacy, Trust | 25–30% |
| Pricing, Licensing, Support | 10–15% |
Notice something?
Apps & services dominate.
Domain Breakdown — What You Actually Need to Know
1. Cloud Concepts (5–10%)
This is foundational:
- SaaS vs PaaS vs IaaS
- Public vs private vs hybrid cloud
- Benefits of cloud computing
Don’t over-study this. It’s basic.
2. Microsoft 365 Apps & Services (45–50%)
This is the heart of MS-900.
Focus on:
- Microsoft Teams (including Teams Phone)
- SharePoint Online
- OneDrive
- Exchange Online
- Microsoft 365 Copilot
- Viva
- Power Platform basics
I’ve seen at least 4–6 Teams scenario questions per exam recently.
Understand use cases, not buttons.
3. Security, Compliance & Trust (25–30%)
This section has grown heavier.
Know:
- Microsoft Entra ID (formerly Azure AD)
- Microsoft Intune
- Microsoft Defender XDR
- Microsoft Purview
- Zero Trust principles
- Compliance Manager
- Data Loss Prevention
Zero Trust isn’t just a buzzword. It’s tested conceptually.
4. Pricing, Licensing & Support (10–15%)
Students struggle here.
Know:
- Difference between E3 vs E5
- Add-ons
- Enterprise vs Business plans
- Support offerings
- Service lifecycle
Licensing questions are often scenario-based.

https://www.leads4pass.com/ms-900.html
Use it to identify weak domains.
Don’t memorize answers. Understand why.
Common Mistakes I’ve Seen (And How to Avoid Them)
After coaching 1,200+ candidates, patterns repeat.
❌ Memorizing Definitions
The exam tests scenarios.
❌ Ignoring Licensing
10–15% is enough to fail you.
❌ Skipping Copilot
Yes, it appears.
❌ Overstudying Cloud Basics
It’s only 5–10%.
Be strategic.
Exam Day Strategy (Simple but Effective)
Here’s my rule:
- First pass: answer everything you’re confident about
- Mark uncertain questions
- Return with fresh perspective
If stuck between two answers:
- Choose the one aligning with Microsoft best practices
- Think “Zero Trust first”
Also — don’t panic if first 5 questions feel hard. That’s common.
Real Career ROI from MS-900
Let me share real examples.
- Help desk tech → promoted to M365 admin within 6 months
- Non-IT project manager → moved into M365 rollout project
- Sales rep → transitioned to solutions consultant
MS-900 certification signals structured understanding.
It’s credibility.
Your Next Step After MS-900
If you pass MS-900, consider:
- SC-900 (Security Fundamentals)
- MS-102 (Microsoft 365 Administrator)
- AZ-900 (Azure Fundamentals)
Think of MS-900 as your launchpad.
