Microsoft Work IQ APIs Target Enterprise Agents

Microsoft announced the Work IQ APIs on June 2, 2026, as a new API surface for agents working with Microsoft 365 data and apps. The APIs are designed to give agents richer context, simpler tool access, and enterprise controls inside the Microsoft 365 trust boundary. The announcement frames Work IQ as the intelligence layer behind Microsoft 365 Copilot and agent workflows. Developers can use Chat, Context, Tools, and Workspaces domains to build agents that reason over business context and take governed actions.

Key Features or Updates

The Work IQ APIs include Chat, Context, Tools, and Workspaces domains for programmatic Copilot access, agent-ready context, Microsoft 365 actions, and safe intermediate state. Microsoft says the APIs will be generally available on June 16, 2026, with public preview available through GitHub.

Impact on Developers

Developers building enterprise agents get an API surface optimized for low-latency context retrieval, tool calling, security, and auditability. The model reduces the need to wire agents directly to many separate Microsoft 365 APIs.

How to use it

Developers can start from the public preview and map agent needs to the four Work IQ domains. IT teams should also review Copilot Credit pricing and the new cost management controls before broader rollout.
