Understanding the Microsoft 365 Administrator Role

This lesson introduces the Microsoft 365 administrator role as an operational, security, and governance responsibility rather than a single checklist of tasks. Learners will understand what administrators manage, how admin responsibilities are divided across roles, and why least privilege, documentation, and change control matter from the first day of administration.

The lesson focuses on the administrator mindset: supporting users, protecting organizational data, keeping services reliable, and making controlled changes through the Microsoft 365 admin center and related admin portals. Later lessons will go deeper into users, groups, licensing, security, compliance, and service-specific administration.
