MS-900: Microsoft 365 Fundamentals

The MS-900 (Microsoft 365 Certified: Fundamentals) exam measured foundational, beginner-level knowledge of Microsoft 365 cloud services, covering cloud concepts, core Microsoft 365 apps and services, security/compliance/privacy/trust in Microsoft 365, and Microsoft 365 pricing, licensing, and support. It was designed as an entry point for people new to Microsoft 365, with no formal prerequisites, and could be used to prepare for other Microsoft certifications without being a required prerequisite for them.

Important update: As of our latest check of Microsoft Learn (September 2026), the MS-900 / Microsoft 365 Certified: Fundamentals certification is listed as retired. Retired exams are no longer offered for new candidates and Microsoft is not currently providing official training for this exam code. If you are researching a current Microsoft 365 credential, check Microsoft Learn Credentials for the certification that has replaced or refreshed this content, since Microsoft periodically consolidates and renames its fundamentals-level exams.

For reference, while the exam was active it followed this format:

• Delivered by Pearson VUE, proctored, 45 minutes to complete the assessment.
• Roughly 40-60 multiple-choice and multiple-response questions covering the four skill areas above.
• Scored on Microsoft's standard 1-1000 scale, with a passing score of 700.
• List price around $99 USD (regional pricing varied).
• Offered in multiple languages including English, Japanese, Spanish, German, Chinese (Simplified), French, Korean, Portuguese (Brazil), Arabic (Saudi Arabia), Russian, Chinese (Traditional), and Italian.

Our practice questions below remain a useful, free way to review core Microsoft 365 concepts (cloud fundamentals, Microsoft 365 apps, security/compliance basics, and licensing/pricing) even though the formal MS-900 exam itself is retired.
