Copilot Inherits Your Mess: Modernizing Microsoft 365 for AI with Richard Harbridge [MVP]

Microsoft 365 Copilot doesn’t arrive in a clean Microsoft 365 tenant. It arrives in an environment that organizations have been building for years — full of SharePoint sites, Teams, OneDrive content, duplicate documents, historic migrations, guest accounts, inconsistent permissions, forgotten workspaces, broken ownership models, and content nobody has reviewed in years.For traditional Microsoft 365 management, much of this technical debt could remain relatively hidden. AI changes that.In this episode of M365.FM, Mirko Peters talks with Richard Harbridge, Microsoft MVP and industry advisor at ShareGate, about why AI readiness is fundamentally connected to Microsoft 365 modernization and governance.The conversation moves beyond the question of how to deploy Copilot and focuses instead on a more important question: What kind of Microsoft 365 environment are we actually giving AI access to?

COPILOT DOESN’T CREATE THE MESS — IT AMPLIFIES IT

One of the central ideas in this conversation is that Microsoft Copilot is not necessarily creating entirely new governance problems. Instead, AI makes existing problems significantly more visible and consequential.Organizations have accumulated years of decisions around permissions, sharing, workspace creation, ownership, migrations, external access, inactive content and collaboration.Richard describes this accumulation using the concept of “sprawl.”Sprawl itself is not automatically bad. A growing number of Teams, SharePoint sites and other resources can be evidence that people are successfully adopting Microsoft 365.The problem begins when that growth happens faster than the organization’s ability to manage it.Temporary permissions become permanent. Old collaboration spaces remain accessible. Ownership changes. Business structures evolve. Content stays online long after its original purpose has disappeared.Copilot then operates on top of that existing environment.

MICROSOFT 365 SPRAWL IS BIGGER THAN TEAMS AND SHAREPOINT

When people hear “Microsoft 365 sprawl,” they often immediately think about too many Teams or SharePoint sites.But Richard argues that sprawl is multidimensional.Organizations can experience workspace sprawl, permission and access sprawl, ownership problems, inactive resources, lifecycle problems, administrative complexity, conditional access sprawl and increasingly integration and connector sprawl.The rise of AI adds another dimension.Microsoft 365 environments increasingly connect data, applications, AI systems and agents. That means organizations need to think beyond individual workloads and start looking at Microsoft 365 as an interconnected ecosystem.Governance can no longer be treated purely as “SharePoint governance” or “Teams governance.”

THE CONFIDENCE GAP IN MICROSOFT 365 GOVERNANCE

Richard shares an especially interesting finding from ShareGate’s research.A very large percentage of IT leaders report being highly confident in their Microsoft 365 governance. Yet a significant portion of those same organizations report that Copilot has surfaced content that users arguably should not have been able to discover — or they suspect this may have happened but do not know how to verify it.That creates an important distinction between having governance controls available and actually having a continuously governed environment.Policies, configuration options and administrative controls alone do not guarantee that an organization understands its current Microsoft 365 state.AI can expose that gap very quickly.

DID MICROSOFT MAKE COLLABORATION TOO EASY?

Microsoft Teams, SharePoint and OneDrive are successful partly because Microsoft has made collaboration extremely easy.But easy collaboration also makes it easy to create more resources.One response organizations have traditionally used is restricting workspace creation. Richard explains why that alone does not solve the problem.A workspace created today may serve...
