Five questions IT leaders are asking right now, answered through the lens of Gartner’s latest research and proven capability. 

Gartner’s May 2026 research note on AI agent governance in Microsoft 365 should be required reading for every IT leader. The report identifies a structural gap that most organizations have been quietly accumulating for years, and it lands at precisely the moment when Microsoft is repositioning SharePoint as the foundational grounding source for Copilot and enterprise agents. That gap is no longer theoretical.

Below are the five questions IT leaders are bringing to their teams right now, and what the data actually says.

Q1: Copilot has been live for months. Why is SharePoint governance suddenly urgent?

Because the nature of SharePoint has just changed. For 25 years, SharePoint was a content repository. Files sat there, employees navigated folder structures to find things, and overshared content was a latent risk largely contained by the simple friction of human discovery.

Copilot and AI agents changed that model entirely. SharePoint is now an active knowledge layer. Every file your employees have access to, including files they have never opened, links shared in 2019 for a project that ended in 2020, and permissions inherited from employees who left years ago, is now fully searchable by any AI query in real time.

“Increased reliance on AI agents that interact with and reason over SharePoint content changes SharePoint from a simple content repository to an active knowledge layer, which IT cannot manage alone.”

– “Close the AI Agent Governance Gap in Microsoft SharePoint With 5 Practical Steps,” Gartner, May 2026

The urgency is not about Copilot itself. It is about what Copilot does to stale, overshared data that most IT teams have been meaning to clean up. Organizations deploying AI on top of unclean data layers are not getting more value from their AI investment. They are expanding their exposure.

How WeActis helps : WeActis maps every share across Teams, SharePoint, and OneDrive against four risk dimensions: who can reach it, how sensitive it is, what they can do with it, and how long that access has existed. Targeted cleanup is then pushed directly to the employees who own the content in Teams within 2 minutes per week. The data layer gets cleaned before AI agents inherit it.

Q2: I keep hearing about “agent sprawl.” Is this something I need to act on now, or is it still theoretical?

Act on it now. In the 2025 Gartner Microsoft 365 and Copilot Survey, the numbers tell a clear story.

• 70% of organizations are worried about Copilot agent sprawl.
• Only 14% say they have the right governance structures to manage AI agents.
• 49% believe IT should own agent creation except in predefined, low-risk use cases.

That last number is worth examining. Nearly half of organizations want IT to control every significant agent. That model will not scale. Microsoft is making agent creation accessible to any M365 Copilot license holder. Site owners can build agents directly in SharePoint today, with a few clicks. The governance framework has to match that reality, not resist it.

Gartner’s recommended response is adaptive governance: a tiered model in which simple, low-scope SharePoint agents are governed locally by site owners, while complex, cross-functional, or high-risk agents are routed through central IT review and approval. The framework should be proportional to agent complexity and risk.

How WeActis helps : WeActis supports this model from the data side. Its Security Models define baseline configurations for Teams and SharePoint sites, enforcing consistent permission structures and access review cadences across the tenant. When site owners operate within defined security models, the agents they build inherit a cleaner, better-governed data layer. IT keeps the policy guardrails. Execution becomes distributed.

Q3: Gartner says site owners should become “AI stewards.” What does that actually mean for my team?

It means your team’s role shifts from doing the governance to enabling the governance. That is a meaningful distinction.

“The increased emphasis on SharePoint as the core grounding source for Microsoft 365 Copilot means that site owners must transition from passive content managers to active AI stewards.”

– Gartner, May 2026

Site owners’ responsibilities now include content cleanup and validation, permissions management, and governance of the full lifecycle of agents in SharePoint, from initial creation through to decommissioning. These activities have to shift from occasional exercises to standard, regular governance that fits into daily, weekly, and monthly work cycles.

For most IT teams, the instinct is to absorb that responsibility. That path leads to the same governance backlog that has been growing for years, now with agent lifecycle management added on top. The productive shift is to equip site owners with the tools and context they need to act, then hold them accountable.

How WeActis helps : Employees receive contextual nudges in Teams about their own risky shares, overshared content, and stale guest access. They act on their own data, within IT-defined guardrails. IT sees the trend lines without running the reviews manually.

At Biron Health Group, this model achieved 78% employee engagement and resulted in the revocation of over 150,000 risky shares, with a measurable reduction in access-related IT ticket volume. The IT team did not run the reviews. The owners did.

Q4: Microsoft provides native governance tools for SharePoint. Is that enough, or do I need third-party tooling?

Gartner’s assessment is direct: native tools surface the problem. They do not fix it at scale.

“While Microsoft does provide native governance capability, the tools are largely aimed toward administration roles, with automation and remediation functionality lacking.”

– Gartner, May 2026

Microsoft’s native offerings, SharePoint Advanced Management, SharePoint Admin Agent, and Agent 365, are tenant-level tools built for administrators. They show what is wrong across the tenant. They do not push cleanup to the employees who own the content, and they do not provide the site-owner-level visibility that distributed governance requires.

Gartner recommends bridging native governance gaps with third-party tooling, specifically to close gaps in visibility, automation, and delegation at scale. The decision is not between Microsoft native tools and third-party tools. It is about recognizing that detection without remediation is not governance.

How WeActis helps : WeActis turns admin-level signals into employee-level actions, inside Teams, without requiring IT to be the intermediary for every remediation. It connects to Microsoft Graph and integrates with Microsoft Purview, amplifying the investments already made in native governance rather than replacing them.

Q5: How do we make our SharePoint data genuinely AI-ready before we expand Copilot access?

Start with the data layer, not the agent layer. Before worrying about which agents are governed correctly, the content that those agents will reason over needs to meet basic hygiene standards.

Gartner identifies three categories of content hygiene risk that become governance failures at AI speed: redundant, obsolete, or trivial content; overshared content; and content with missing or inconsistent metadata and sensitivity labels. Each of these represents a potential source of hallucinations, inaccurate outputs, or data exposure when agents start querying them at scale.

The practical sequence is: discover the scope of your exposure, evaluate what is genuinely at risk, and remediate through the employees who own the content. That sequence has to be continuous, not a one-time campaign.

How WeActis helps : The Discover phase delivers a real-time inventory of every share across Teams, SharePoint, and OneDrive. The Evaluate phase applies the four-component risk model to identify priority items. The Remediate phase pushes cleanup to data owners in Teams with one-click revocation, so the backlog actually moves.

A major Canadian financial institution ran this process across a partial deployment of 10,000 employees and revoked 1.2 million obsolete shares, applied 8,300 security models to SharePoint and Teams sites, and surfaced 55 million files for review. That scale of cleanup is structurally unreachable through IT-only governance projects.

The Governance Gap Won’t Close Itself

The gap Gartner describes is real, and Microsoft’s AI roadmap for 2026 will widen it for organizations that do not act. The good news is that closing it does not require a transformation project. It requires a mechanism that puts cleanup in the hands of the people who created the access in the first place, within the tool they already use, while IT keeps the guardrails centralized.

WeActis deploys in days, requires no policy rewrite or governance committee, and produces auditable evidence of risk reduction from the first week.
