Agent 365 can now sync agent registries from AWS and Google Cloud. Without configuring those connections, the registry shows only Microsoft agents and not the full agent population.
Microsoft's May 1, 2026 What's New in Agent 365 announcement introduced registry sync, allowing organizations to connect the Agent 365 registry to external agent platforms. Initial preview connections include Amazon Web Services and Google Cloud, with additional partner platforms planned. When connected, agents built on those platforms appear in the Agent 365 unified registry with governance actions including agent deletion available directly from the registry interface. Without registry sync connections configured, Agent 365 shows only Microsoft-hosted agents.
GOVERNANCE IMPLICATION
Registry sync addresses the most significant structural limitation of Agent 365 at GA launch: its scope was restricted to Microsoft-hosted agents. For organizations building agents on AWS Bedrock, Google Vertex AI, or other non-Microsoft platforms, the Agent 365 registry has been functionally incomplete as a single governance surface. Registry sync begins to close that gap. The governance implication is structural: organizations that have positioned Agent 365 as the centerpiece of their agent governance posture are governing an incomplete population until registry sync connections are configured and verified. A registry that shows Microsoft agents but not AWS agents does not represent the full risk surface, and presents false completeness to any examiner reviewing the governance posture.
SCENARIO
A financial services firm standardizes on Agent 365 as its enterprise agent registry. The CISO reports all agents are registered and governed. Two quarters later, an audit identifies 23 agents built by the data science team on AWS Bedrock. Those agents were never connected to registry sync: the data science team did not know it needed to be configured. The CISO's board report was accurate for Microsoft-hosted agents and incomplete for the full agent population.
THE GOVERNANCE QUESTION
Your Agent 365 registry is complete only for Microsoft-hosted agents until you configure registry sync connections for every platform your organization builds agents on. Which non-Microsoft platforms in your environment are currently unconnected to the registry, and who is accountable for configuring and verifying those connections before the next governance review?
CONTROL GAP
Registry sync connections must be manually configured per platform. Organizations that do not actively configure connections will have a registry that appears complete while remaining blind to agents running on non-Microsoft platforms.

AgentsMicrosoft Copilot Studio published April 2026 feature updates on May 11, 2026, authored by Nitasha Chopra, VP and COO of Copilot Studio. Key releases include the Analytics Viewer role reaching GA providing read-only access to agent analytics separated from configuration rights; agent nodes embeddable directly into workflows to delegate AI reasoning within deterministic automation; MCP server-enabled tools in preview for external system connectivity within workflows; and a centralized admin-controlled DLP-enforced environment for the Workflows Agent. The post also confirms Microsoft Agent 365 is now generally available as the centralized control plane for agents.

AgentsMicrosoft's 2026 Work Trend Index Annual Report, published May 5, 2026, includes the first WTI telemetry on AI agent volume. Active agents on Microsoft 365 grew 15x year-over-year across all customer segments, rising to 18x in large enterprises. This is the first time Microsoft has disclosed agent volume scale as part of its annual workforce research.

AgentsMicrosoft's May 1, 2026 What's New in Agent 365 announcement introduced a Shadow AI page within Agent 365, enabled by Microsoft Defender and Microsoft Intune. The page identifies local agent activity on Windows devices: agents installed directly on company machines outside IT and security visibility. These local agents can read files, execute code, and act on behalf of users without touching managed cloud services, and were previously invisible to the Agent 365 registry. The Shadow AI page is the first native Microsoft control surface for detecting this category of ungoverned agent.
