The Complete Microsoft 365 Administrator Certification Path
Microsoft 365 administration is where most of Microsoft's enterprise business actually happens. Every large employer runs a tenant, every tenant needs an admin, and the certifications for it are more specific than most Microsoft paths — because the discipline is more specific.
The six‑exam ladder below spans from MS-900 to AZ-140, and the order matches how M365 admin roles are hired against. Fundamentals opens the seat, the SC and MS papers add the specialisms that put “senior” on the job title.

Start here: MS-900 is the hiring floor
Microsoft 365 Fundamentals (MS-900) is the paper the junior tenant admin adverts filter on. It is 60 questions in 60 minutes and heavy on licensing, which is unglamorous but is what a working admin actually does.
Core: MS-102 and SC-300
Microsoft 365 Administrator (MS-102) and Identity and Access Administrator (SC-300) are the paired papers for the core M365 admin role. Sit them in either order; hiring managers look for both.
Go deeper: MS-721, SC-401 and AZ-140
Collaboration Communications Systems Engineer (MS-721) covers Teams voice. SC-401 (Administering Information Security in Microsoft 365) is the security specialism, and AZ-140 (Configuring and Operating Azure Virtual Desktop) covers the AVD estates most large M365 admins now also run.
