ExploreAbout this exam
MS-102: Microsoft 365 Administrator is the one required exam for the Microsoft 365 Certified: Administrator Expert credential. Microsoft frames the role as the integrating hub across Microsoft 365 workloads - someone who coordinates with architects and with the administrators responsible for infrastructure, identity, security, compliance, endpoints, and applications. Candidates should have functional experience across Microsoft 365 workloads and Microsoft Entra ID, have administered at least one of them, and know networking, Active Directory Domain Services, DNS, and PowerShell. The skills measured as of April 28, 2026 cover four areas: deploy and manage a tenant (25–30%), Entra identity and access (25–30%), security and threats with Microsoft Defender XDR (30–35%), and compliance with Microsoft Purview (10–15%). The Exam Details page publishes a different split, so treat the study guide figures as authoritative for the current version. Earning the certification also requires at least one qualifying associate certification. Prepare with the free study guide, hands-on tenant administration, the free practice assessment, and the exam sandbox. You need a score of 700 or greater to pass. The exam and certification both retire on November 30, 2026.
What you'll study
About MS-102 preparation
What score do I need to pass MS-102?
A score of 700 or greater is required to pass. Microsoft states this on both the exam details page and the study guide, and links to its explanation of how exam scores work. Microsoft does not publish how individual skill areas are weighted within that scaled score.
Which skill areas carry the most weight?
Per the study guide's skills measured as of April 28, 2026: Defender XDR security is largest at 30–35%, tenant deployment and Entra identity and access are 25–30% each, and Purview compliance is 10–15%. The Exam Details page shows a different split (10–15%, 25–30%, 35–40%, 15–20%), so confirm which version you are sitting.
Do I need a prerequisite certification before taking MS-102?
To earn Microsoft 365 Certified: Administrator Expert you must earn at least one associate certification: Endpoint Administrator, Teams Administrator, Identity and Access Administrator, or Information Security Administrator. The exam details page lists three of these while the certification page lists four. Passing MS-102 alone does not award the certification.
Can I still take the exam after November 2026?
No. The exam retires on November 30, 2026, at 11:59 PM Central Standard Time, and the certification retires on the same date - after that it can neither be earned nor renewed. Microsoft advises completing the exam before the retirement date so it is still applied toward the certification.
How long is the certification valid, and how do I renew it?
Microsoft associate, expert, and specialty certifications expire annually. Renewal is free: you pass an online assessment on Microsoft Learn instead of retaking MS-102. Because this certification retires on November 30, 2026, that renewal path stops being available after the retirement date.
How many questions are on the exam and how much time do I get?
The Microsoft pages for MS-102 do not publish an item count or a time limit, so treat any specific number you see elsewhere with caution. Use the free exam sandbox to preview the environment, and request an accommodation if you need extra time or any other adjustment.
In which languages is MS-102 available?
English, Chinese (Simplified), German, Spanish, French, Japanese, and Portuguese (Brazil). The English version was updated on April 28, 2026, and localized versions are typically updated about eight weeks later but can lag that schedule. If the exam is not offered in your preferred language, you can request an additional 30 minutes.
What does the exam cost, and how should I register?
Price depends on the country or region where the exam is proctored, is subject to change without notice, and excludes applicable taxes. Register with a personal Microsoft account: Microsoft strongly recommends it, because exam records tied to a work or school account are lost and unrecoverable if you leave the organization.
How hard is MS-102, and what trips candidates up?
It is an expert-level exam that assumes functional experience across all Microsoft 365 workloads and Microsoft Entra ID, and that you have administered at least one workload. The usual failure mode is depth without breadth - going deep on one workload while neglecting Defender XDR, which holds the largest share of the skills measured.
What happens if I fail - can I retake the exam?
The MS-102 pages do not publish a retake waiting period or retake fee; those rules live in Microsoft's exam policies and FAQ, which you should read before scheduling. Practically, use your score report to identify weak skill areas, then work through the free practice assessment and exam sandbox before rebooking.
