A complete Microsoft 365 tenant built from scratch for a fictional company "Magister Operis Systems" demonstrating real-world admin workflows from user creation to security policy enforcement.
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.
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.
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.
Each runbook covers a distinct admin workflow. Click a card to download the PDF file.
