Microsoft Build 2026 Preview: Agent 365 GA and Shadow AI Management

View original source →

Microsoft Build 2026 approaches its June 2-3 date with pre-event announcements signaling a conference focused on AI agents as production infrastructure rather than developer preview features.

The San Francisco location — a deliberate move from Seattle — positions Microsoft at the center of the AI startup ecosystem.

Announced capabilities:

- Agent 365 general availability: Microsoft's enterprise AI agent platform moves from preview to production-supported infrastructure - Shadow AI management: Preview capabilities for discovering and managing AI agents deployed without IT oversight - Startup program expansion: AI credits, free specialized AI support engineers for six months, and co-sell program placing startup solutions in front of Microsoft's enterprise salesforce

Agent 365 reaching GA marks the transition point where organizations deferring deployment pending production support can proceed with planning.

The shadow AI management capability addresses one of the most underreported enterprise AI governance risks. Employees deploying AI agents that operate on corporate data without IT visibility or controls is happening at scale. Providing discovery tools acknowledges the problem exists.

Enterprise IT and AI operations leaders should prioritize evaluating Agent 365 GA capabilities this week. The shadow AI discovery tools address an immediate governance gap that most organizations have not formally assessed.

Microsoft's acknowledgment of shadow AI as a managed problem is an invitation to formalize your organization's AI agent inventory process.

Why It Matters: Agent 365 reaching GA enables enterprise production deployment of Microsoft's agent platform. Shadow AI management tools address an underreported governance gap — most organizations don't know what AI agents employees have deployed.
