Office 365 for IT Pros 2025 Edition

Why buy separate books to learn about Microsoft 365, SharePoint Online, Exchange Online, OneDrive for Business, Microsoft Teams, eDiscovery, Information Protection, Compliance, and PowerShell? Office 365 for IT Pros covers all these topics and much more.

Intensely practical and offering the most up-to-date coverage of its topics, Office 365 for IT Pros (2025 edition) is the eleventh yearly release in a series first released at the Ignite conference in May 2015. This text is essential reading if you want to maximize your use of Microsoft 365. Because of the large number of updates Microsoft releases monthly for Entra ID, Exchange Online, SharePoint Online, Teams, OneDrive for Business, and the rest of the Microsoft 365 ecosystem, we publish a new book every month for our subscribers to download and enjoy. It’s the equivalent of getting a completely up-to-date book every month.

Your package includes the main Office 365 for IT Pros eBook and a separate eBook about Automating Microsoft 365 with PowerShell and the Microsoft Graph. Both books are updated monthly, The latest updates are from 1 October 2024. We're currently at monthly update #112, so we think we've mastered this process!

We release the books in both EPUB and PDF formats. Many of our readers convert the EPUB version to MOBI to read the book on Amazon Kindle devices.

Hundreds of Updates Annually

Satya Nadella, the Microsoft CEO, acknowledges that Microsoft ships hundreds of updates for Office 365 apps every year. Depending on what licenses are owned by a tenant, a tenant administrator might have to cope with seven hundred individual changes annually. Until we publish the next edition, your subscription allows you to download monthly updates to keep pace with developments in Entra ID, Exchange Online, SharePoint Online, Planner, Teams, and more, meaning that Office 365 for IT Pros continues to be a valuable reference long after you first read it. To give some insight into the volume of changes we process, the Office 365 for IT Pros team processed over 450 major updates during the lifetime of the 2024 edition.

Subscribers can download the latest files from their Gumroad account or by using the link in the receipt emailed to them on purchase. For more information, see our FAQ. Full details of changes made to the book are in our change log.

Tracking Cloud Developments

Written by a team of highly experienced authors, most of whom are Microsoft Most Valuable Professionals (MVPs), Office 365 for IT Pros (2025 edition) is a practical, hands-on reference, based on years of hard-won experience acquired from working on projects since Microsoft launched Office 365 in June 2011. Because we keep an eye on what Microsoft does, you don't have to worry about making decisions based on outdated material - we do the work for you. We explain how the technology works and why it works as it does, including when new technology like Copilot for Microsoft 365 comes along.

And because we’re always up-to-date, Office 365 for IT Pros is totally unlike any printed technical reference you’ve ever used.

The Massive Scale of Microsoft Cloud Services

In October 2023, Microsoft reported that they have sold over 400 million paid seats for Office 365 (enterprise plans). At the same time, Teams had 320 million monthly active users. Office 365 for IT Pros (2025 edition) includes in-depth coverage of essential business productivity features such as Teams, Microsoft 365 Groups, Stream, Planner, Power Automate, Power Apps, Exchange Online, SharePoint Online, Viva Engage, and OneDrive for Business. You'll learn about the Microsoft Purview solutions like eDiscovery, data lifecycle management (retention), and data loss prevention. We explain how to exploit the audit log to understand what's really happening inside a tenant. A chapter on Microsoft Information Protection teaches you how to protect messages and documents with sensitivity labels.

Chapters

Office 365 for IT Pros chapters are:

1. The Microsoft 365 Ecosystem and Office 365: Outlining the role Office 365 plays in the Microsoft 365 ecosystem, how Microsoft’s data centers and networks serve users, and the commercial success of the service. This chapter also discusses the operation of the Microsoft 365 cloud, the issues that might occur, and how you mitigate any potential problems to ensure a successful deployment.

2. Managing Identities: Without an identity, no one can access or use a Microsoft 365 service. This chapter dives into the role of Entra ID, including hybrid directories and authentication, exploring topics like conditional access policies and cross-tenant access policies.

3. Managing Tenants: Covers the basics of managing a Microsoft 365 tenant from permissions and roles to Service Health and managing support requests.

4. Managing Users: A deep dive into how Entra ID user accounts work within a Microsoft 365 tenant and how to manage accounts during their lifecycle.

5. Managing Exchange Online: Exchange Online is one of three core Microsoft 365 workloads. This chapter covers details of how to manage Exchange Online and the differences between it and its on-premises counterparts. We explain what apps store in Exchange Online mailboxes and how to make use of functionality like archive and inactive mailboxes.

6. Managing Mail Flow: Exchange Online processes a huge volume of inbound and outbound email. This chapter covers how to manage mail flow, connectors, transport rules, Exchange Online Protection policies, Microsoft Defender for Office 365 policies, email attack simulations, email investigations, threat explorer, and more. It also delves into topics such as DANE for SMTP, MTA-STS, Sender Rewrite Scheme, DKIM, and SPF

7. Managing SharePoint Online: SharePoint Online is the second core workload delivering a document management service to Office 365 apps like Teams, Planner, and Viva Engage. It also encompasses OneDrive for Business, used for personal user storage. This chapter also reviews important components associated with SharePoint Online, like Microsoft Search, Syntex, and Viva Topics. Microsoft makes the point that Microsoft 365 Copilot depends on “a rich abundance of data stored within Microsoft 365 repositories.” Make sure that SharePoint Online and OneDrive for Business work by absorbing the knowledge from this chapter.

8. Managing Microsoft 365 Tasks: Tasks span anything from personal tasks created with Outlook or To Do to group tasks created in Planner (and maybe even Project). Microsoft 365 treats tasks as a common object type supported by multiple apps, so we dive into the creation and management of tasks in Planner, Outlook, and Teams, including the plan-only versions used by Microsoft Loop task list components.

9. Managing Video: Office 365 has long boasted a video portal. The current implementation is called Stream on SharePoint and reflects the use of SharePoint Online and OneDrive for Business to store videos. This chapter explains how Stream works and how to tweak the Stream web app and player.

10. Managing Groups: Microsoft 365 groups is a core identity and membership service used by apps like Teams, Planner, and Viva Engage. This chapter reviews how the Groups service works and covers details of other groups used by Microsoft 365, including distribution lists, dynamic distribution lists, and dynamic Entra ID groups.

11. Teams Architecture and Structure: Now with more than 300 million monthly active users, Teams is the third core Microsoft 365 workload. Teams consumes services drawn from across the Microsoft 365 ecosystem to deliver its mixture of messaging, meetings, voice, video, and app services. This chapter describes the architecture and structure of Teams and the fundamentals of how Teams works.

12. Managing Teams: Nice as it is to have everyone collaborating and connecting in Teams, the app needs to be managed, especially in large deployments. This chapter discusses the essential management tasks needed to keep Teams in good working order.

13. Managing Teams Calling and Devices: Many organizations use Teams and the Microsoft Phone system as the foundation for their voice and calling infrastructure. This chapter covers how Teams voice works and how to select, deploy, and manage devices used with Teams.

14. Managing Clients: This chapter tells you how to manage the different clients used by Office 365 applications, including Microsoft 365 apps for enterprise, Teams, and mobile clients.

15. Managing Devices with Intune: Microsoft Intune allow organizations to manage devices connected to Microsoft 365. This chapter covers how to approach mobile device management.

16. Managing Compliance: Compliance is a big topic. Microsoft 365 plans enable functionality like data lifecycle management (retention labels and policies) and information barriers, both covered in this chapter along with the legacy (but still powerful) Exchange Online mailbox retention policies.

17. Managing eDiscovery: Once information is under control, it’s nice to be able to find data when you need it. This chapter covers how content searches, Microsoft Purview eDiscovery standard, and Microsoft Purview eDiscovery premium work.

18. Managing Data Loss Prevention: Information leakage is a terrible thing. Data Loss Prevention (DLP) policies help users inadvertently share confidential or sensitive information when they shouldn’t. This chapter explains how DLP works in Exchange Online, SharePoint Online, and Teams, and how to build custom sensitive information types for use within Microsoft 365 compliance solutions.

19. Managing Information Protection: Since 2016, Microsoft has invested heavily in building out an information management framework to allow Microsoft 365 tenants to protect email and documents with rights-management based encryption. We explain how sensitivity labels and Microsoft 365 message encryption work and how to use sensitivity labels for container management (teams, sites, and groups).

20. Managing Reporting and Auditing: In any reasonably-sized tenant, users generate tens of thousands of actions daily, most of which are captured as events in the unified audit log. This chapter discusses how the audit log works and more importantly, how to retrieve and make sense of the audit events found there to answer questions about who did what and when. Office 365 Cloud App Security is also covered along with lots of recommendations about how to generate reports about user activity.

21. Managing Power Platform: The Power Platform is a great way to automate common user and administrative operations. Although designed to work without anyone needing to write any code, Power Automate needs to be understood. We explain how to exploit the major features of Power Automate and Power Apps here.

22. Sponsor content: CoreView sponsors Office 365 for IT Pros (2025 edition) and helps us keep the cost of the book to the same price it's been since 2015. As a major independent software vendor (ISV), CoreView has many products designed to help tenant administrators. This chapter explains how CoreView software helps to deliver effective deployments of Microsoft 365 and its associated technology.

It might take you more than 30 hours to read the 660,000+ words in Office 365 for IT Pros (2025 edition), but those hours will save you so much time in deploying and managing that the effort will be well worthwhile. After all, hiring a consultant to explain any of the topics covered in Office 365 for IT Pros will likely cost you twice what we charge for the book, so subscribing is really a great deal!

New eBook for Office 365 for IT Pros (2025 Edition)

Automating Microsoft 365 with PowerShell: The ability to automate common administrative processes is critical to maintaining a secure, reliable Microsoft 365 tenant.

Finally, the book includes extensive coverage of the Microsoft Graph PowerShell SDK and explains how to interact with users, groups, licenses, teams, sites, and many other Microsoft 365 objects using SDK cmdlets.

Across the book, you’ll find in-depth instructions (including over a thousand examples of using PowerShell and the Microsoft Graph) for provisioning, exploiting, and administering Microsoft 365 workloads.
