Exchange Online Management with PowerShell

Exchange Online Management with PowerShell teaches you how to manage, automate, and secure Microsoft 365 email environments using real-world PowerShell scripts and administrative best practices.

Exchange Online Management with PowerShell is a practical, hands-on guide to managing Microsoft 365 email environments with precision, efficiency, and confidence.

While the Exchange Online Admin Center is sufficient for basic tasks, it quickly reaches its limits in real-world enterprise environments. PowerShell is where Exchange Online administration truly comes alive—enabling automation, bulk operations, advanced reporting, and deep security configuration that simply cannot be achieved through the graphical interface alone.

This book was written for IT professionals who want to move beyond manual, repetitive administration and adopt a scalable, script-driven approach to Exchange Online management.

You will begin by establishing a solid foundation: understanding how Exchange Online PowerShell works, how to connect securely using the Exchange Online Management Module, and how to prepare your environment for automation. From there, the book guides you through the most common and critical administrative tasks—managing users and mailboxes, configuring permissions, handling shared resources, and controlling mail flow.

As you progress, the focus shifts to policies, compliance, and security. You will learn how to manage retention and DLP policies, audit mailbox activity, and integrate Exchange Online administration with Microsoft Purview. Dedicated chapters cover security hardening, multi-factor authentication for PowerShell access, and protecting your organization against spam, phishing, and malicious content.

Advanced chapters address hybrid scenarios, bulk operations, delegated administration, and performance optimization. You will also learn how to generate meaningful reports, monitor your environment proactively, and troubleshoot common Exchange Online issues using PowerShell-based diagnostics.

Throughout the book, every concept is reinforced with practical examples and real-world scripts. The emphasis is on clarity, safety, and repeatability—helping you build automation that is not only powerful, but also maintainable and secure.

If you manage Exchange Online in a professional environment, this book will become an essential part of your administrative toolkit.
