Microsoft 365 Certified: Copilot & Agent Administration Fundamentals (AB-900)

Microsoft 365 Copilot and agents create new administration, security, and data-governance pressure for IT teams. This beginner-level AB-900 course helps IT Directors standardize foundational knowledge before assigning staff to support Copilot rollouts, Microsoft 365 administration, and Purview-based compliance workflows. It is a strong fit for help desk staff, junior Microsoft 365 admins, security newcomers, and Team Leads who need shared vocabulary across Entra ID, admin centers, Defender XDR, Purview, Copilot governance, and agent administration. Plan for roughly 18.5 hours per learner across 21 skills, plus time for review or exam prep. For change management, this course works best as a team baseline before production policy changes, especially around conditional access, DLP, oversharing, insider risk, and eDiscovery. CBT Nuggets Playlists can help Training Managers assign the course by role, while Team Reporting helps IT leaders track completion and readiness.

IT teams complete this training to reduce the risk of poorly governed Microsoft 365 and Copilot adoption. The course connects day-to-day admin work with security and compliance controls across Azure tenants, Microsoft 365 admin centers, Defender XDR, Purview, Copilot, and agents.
