Microsoft 365 Administration Foundations

Manage Compliance Using Microsoft Purview is the practical guide you wish you had before you touched retention, labeling, or DLP in a live tenant. Microsoft Purview can feel like a maze of menus, policies, and overlapping features. This book turns it into a clear, skills-first path so you can protect sensitive data, reduce compliance risk, and build controls that users can actually live with.

Written for real-world Microsoft 365 admins, you will learn how Purview identifies sensitive content, how labels and retention work together, and how to deploy Data Loss Prevention across the places people work every day: email, SharePoint, OneDrive, Teams, and endpoints. Along the way, you will see how to monitor adoption using Content explorer and Activity explorer, respond to alerts without burning out your team, and tune policies so they protect the business without constant false positives.

Inside you will learn how to:

• Build sensitive information types using keywords, keyword lists, and regex
• Design retention labels, label policies, and retention policies that match business reality
• Roll out sensitivity labels that protect data and still allow collaboration
• Monitor label usage and investigate risky behavior using Purview's explorer tools
• Deploy DLP for Exchange, SharePoint, OneDrive, Teams, and Endpoint DLP
• Triage and respond to DLP alerts, events, and reports with a repeatable process
