The Lab Setup

To practise M365 administration hands-on, I designed a realistic fictional scenario: Magister Operis Systems (MOS), a Berlin company with 23 simulated users across 7 departments. I built their full M365 tenant from scratch, treating it exactly as I would a real client environment.

📋

What a Runbook Is

Each runbook is a step-by-step admin guide with real screenshots from the M365 Admin Center, Entra ID, and Teams, documenting exactly what I did, what errors appeared, and how I resolved them.

🎯

Why I Built This

To demonstrate M365 administration in a structured, professional way, not just knowing the theory, but executing and documenting it as an IT Systems Administrator would on the job.

⏱ 45 min 🟡 Intermediate Entra ID P1 Required
⚠ Lab limitation: This runbook could not be executed, Conditional Access requires Entra ID P1, which is not included in M365 Business Standard. The runbook documents the intended configuration based on Microsoft documentation.
