Microsoft updates guidance for governing AI agents in Microsoft 365

Microsoft has released version 3.2 of its whitepaper on administering and governing agents. The update adds detailed instructions for using the new Copilot Agent Store, where admins can control agent discoverability and distribution across the tenant. It introduces zone-based governance with three zones matched to risk levels, plus controls for agent sharing. Security and monitoring now integrate Microsoft Agent 365 with tools like Copilot Studio, SharePoint permissions, and Purview. The previous version had been downloaded 65,000 times.
Admins previously managed AI agents in silos, with sharing risks echoing unchecked Teams creation and external document access. Permissions scattered across tools left gaps for compliance issues, much like lingering guest access on SharePoint sites. Zone-based controls now map agents to low, medium, or high risk, using Environment Groups in Copilot Studio for tenant-wide enforcement. This creates a unified audit trail via familiar M365 admin centers, turning agent sprawl into a contained asset like hub sites.
Analysis
Agents will sprawl just like your 300-plus Teams if you skip this framework now. Map your Copilot Studio environments to the three zones today and link agent sharing to your SharePoint external policies, preempting the next support ticket wave.
