power-platform-m365-admin-practice

This repository documents my hands-on learning journey with Microsoft 365 administration. I use it to explore how identity, access and basic security concepts work in practice, while learning how Microsoft 365 and Power Platform admin tools behave in real scenarios.

The focus is on learning and understanding fundamentals not on production automation or advanced architecture.
