The Problem: AI Agents Without Guardrails 

Most organizations have already deployed AI agents. Some were built by developers in Azure AI Foundry or Copilot Studio. Others were spun up by individual employees using SharePoint or Microsoft Teams. And many IT leaders have no idea how many agents exist in their environment, who owns them, or what data they can access. 

Steve Corey, Principal Consultant and Microsoft MVP at Quisitive, describes it directly: organizations are dealing with the “Wild West” of AI agents, the same way they once struggled to manage SharePoint sites sprawling across the organization with no clear ownership or governance. 

The difference now is that agents do more than store information. They take action. They modify files, query databases, send emails, and interact with business-critical systems. The stakes of poor governance are significantly higher. 

That is the problem Agent 365 is designed to solve.

What Is Agent 365? 

Agent 365 is Microsoft’s governance and management platform for AI agents across the Microsoft 365 ecosystem. Microsoft refers to it as the “control plane for agents.” 

Rather than replacing the tools IT teams already use, Agent 365 brings them together. Defender, Microsoft Entra, and Microsoft Purview have long been used to manage users, protect data, and enforce compliance policies. Agent 365 extends that same infrastructure to cover AI agents, applying familiar controls to a new category of entity in your organization. 

The core idea is straightforward: treat AI agents like you would treat employees or contractors. Give them identities, assign them licenses, apply access controls, audit their activity, and manage their lifecycle from onboarding to offboarding.

Why Does This Matter for Enterprise IT Leaders? 

Three groups have a direct stake in whether AI agents are governed well: 

1. Security teams want to know that agents are not accessing systems or data they should not touch, and that any suspicious behavior is detected quickly. 
2. Business leaders want to know whether agents are delivering measurable value and whether the investment in agentic processes is paying off. 
3. IT administrators need a single place to see what agents exist, who owns them, and what policies are applied to them. 

Until Agent 365, none of those groups had a reliable way to get answers. Reporting was scattered across the SharePoint admin center, the Teams admin center, the Power Platform admin center, and Azure, and most administrators did not have access to all of those locations simultaneously. 

Key Features of Agent 365 

1. Agent Registry: A Single Inventory of Every Agent 

The agent registry is a centralized catalog of every AI agent deployed in your environment, regardless of where it was built or how it was deployed. This includes: 

• SharePoint agents 
• Copilot Studio agents 
• Azure AI Foundry agents 
• Agents built with the Agent SDK or other developer frameworks 
• Agents deployed outside the Microsoft ecosystem (such as in AWS), provided the developer integrates with the Agent 365 SDK 

Jimmy Ledbetter, VP of AI Strategy and Solutions at Quisitive, describes the registry as the “HR department for your agents.” Just as HR maintains a record of every employee, the registry tells you where every agent lives, who owns it, what it can access, and what policies govern it. 

The registry also provides a graphical visualization of all agents, grouped by the platform they were deployed on, so IT teams can quickly identify what is running and drill into details for any individual agent. 

2. Agent ID: Giving Agents an Identity in Microsoft Entra 

One of the most significant architectural changes in Agent 365 is the introduction of Agent ID. Every agent provisioned through Agent 365 receives its own identity in Microsoft Entra, like how a user account is created when someone joins the organization. 

What that means in practice: 

• Agents can be assigned licenses (for example, Power Automate Premium or Power Apps Premium) 
• Conditional access policies can be applied to agents, restricting what they can do and where they can operate 
• Each agent gets its own mailbox and can receive messages in Teams 
• Agents appear in the organizational chart, reporting to the user who requested them 
• All activity tied to a specific agent instance traces back to the responsible human user 

This last point is particularly important for accountability. When a user requests an agent, Agent 365 creates a unique instance of that agent tied to that individual. If the agent does something unexpected, the audit trail leads back to a specific person. 

3. Lifecycle Management: Handling Ownership Transitions 

One of the most persistent pain points with AI agents is ownership transfer. When an employee who built an agent leaves the organization, that agent often becomes an orphan. It may still be running. It may still have access to sensitive systems. And no one knows what to do with it. 

Agent 365 addresses this with lifecycle management tools that allow administrators to: 

1. Identify agents with no active owner 
2. Reassign ownership with a single-click operation 
3. Decommission or delete agents that are no longer needed 

This mirrors how organizations manage other IT assets, including SharePoint sites, and brings the same discipline to AI agents. 

4. Agent Store Management: Controlling What Agents Users Can Access 

The agent store is the catalog where users can discover and request access to agents, similar to an app store. By default, it surfaces agents from Microsoft, from your own organization, and from third-party publishers. 

With Agent 365, IT administrators can control exactly what appears in the agent store for different groups of users. An HR team can have access to a set of agents relevant to their workflows without those agents being visible to the rest of the organization. New agents can be staged out to progressively larger groups before a full rollout. 

5. Security Integration with Microsoft Defender 

Agent 365 integrates with Microsoft Defender to provide security monitoring that covers agents the same way it covers users. Key capabilities include: 

• Centralized monitoring of all agent activity in a unified Defender view 
• Out-of-the-box threat detection configured to flag suspicious behavior, including jailbreak attempts against agents 
• Advanced hunting capabilities that allow security analysts to query agent activity logs, identify anomalous patterns, and investigate specific incidents 

Zero trust principles apply here. Organizations should not trust agent activity by default. They should be able to verify it. Defender gives security teams the tools to do exactly that. 

6. Compliance and Data Protection with Microsoft Purview 

As agents move from answering questions to taking actions, the risk profile changes substantially. An agent that deletes a file or overwrites a database record by mistake can cause real business harm. 

Purview extends its existing compliance capabilities to cover agentic activity. This includes: 

• Sensitivity labels applied to content that agents can access, limiting what data an agent can read or modify based on the label 
• Audit logs that capture agent activity across all interaction types: agent to human, human to agent, agent to tool, and agent to agent 
• Support for compliance reviews of specific agent instances, the same way you would audit a user account 

One important note: organizations should have their Microsoft 365 environment properly configured for Copilot before deploying agents. Sensitivity labels, access controls, and data governance policies should already be in place. Agents amplify whatever foundation exists in your environment, both the strong parts and the gaps.

How Agent Provisioning Works: Blueprints and Instances 

The provisioning model in Agent 365 is worth understanding before deployment. 

Developers or administrators publish an agent blueprint. Users cannot directly interact with the blueprint. Instead, they request access through the agent store. Once approved (manually or automatically, depending on how the environment is configured), the system creates a unique instance of that agent for that user. 

That instance: 

• Gets its own Agent ID in Entra 
• Inherits all the access controls and compliance policies applied at the blueprint level 
• Appears in the org chart as reporting to the requesting user 
• Consumes an Agent 365 license 

If a user no longer needs the agent and deletes their instance, that license is released. Only active instances consume licenses, not dormant blueprints. 

This model also ensures consistency. Whether 10 users or 1,000 users have requested the same agent, every instance carries the same access controls and compliance policies as the blueprint it was stamped from. 

Measuring ROI: The Agent 365 Dashboard 

The main dashboard in Agent 365 provides a high-level view of: 

• Total number of agents deployed across the environment 
• Active users interacting with agents 
• Time saved, calculated using configurable metrics 

That last item is where the platform becomes useful for business conversations. The time-saved calculation is adjustable. Administrators can configure how many minutes are attributed to specific actions (such as drafting an email or summarizing a document), so the ROI figure reflects how the organization actually values those activities. 

Jimmy Ledbetter frames this as an input into the broader AI governance discussion: “Does it make sense for us to deploy this agent? Not everything needs an agent, but this helps you have that discussion.” 

Getting Started: A Practical Approach for Organizations Starting from Zero 

For organizations that have not yet deployed agents, or are just beginning to explore the space, Corey and Ledbetter recommend a progression: 

1. Start with native, low-code options. Microsoft 365 Copilot agent features built into applications like Excel, Word, and SharePoint are a good starting point. These require no development work and give users and administrators an early look at what agentic behavior looks like in practice. 
2. Use Copilot Studio Lite for simple departmental agents. This is appropriate when one person owns the agent and the use case does not require premium connectors. 
3. Move to Copilot Studio for more complex workflows that require integrations with external systems. 
4. Use the M365 Agents Toolkit in VS Code or Visual Studio for custom-built agents that require code-level control. 

Start with the simplest option that solves the problem, validate that the workflow actually works, and then invest in more sophisticated infrastructure once the use case is proven.

What Agent 365 Does Not Cover (Yet) 

A few limitations worth noting based on the current state of the platform: 

• Collaborative editing of Copilot Studio Lite agents is not yet supported. Ownership can be transferred, but co-authoring is not currently available. 
• Licensing and pricing details were still being finalized at the time of the webinar. Organizations should check current Microsoft documentation for the latest information. 
• Agent 365 is currently in early access through the Microsoft Frontier program. Features are subject to change based on customer feedback. 
• KQL queries for advanced agent activity analysis in Purview require additional configuration. This is an area where working with a Microsoft partner can help organizations set up the right data connections.

Conclusion 

AI agents are already operating in most enterprise Microsoft environments. The question is no longer whether to use them, but whether you have the visibility, controls, and accountability structures in place to govern them responsibly. 

Agent 365 addresses the three most common concerns IT and business leaders raise about AI agents: 

• Are agents secure, and is our data protected? 
• Are agents delivering value? 
• Do we know what agents exist in our environment and who is responsible for them? 

By extending the same identity, security, and compliance infrastructure that already governs users, Agent 365 makes it possible to answer all three questions with data rather than assumptions. 

The “Wild West” era of agent deployment does not have to be permanent. The tools to tame it are available now.
