Agent 365: govern the identity before expanding the fleet

A dated source, a continuing question

Microsoft introduced Agent 365 as a control plane for AI agents on November 18, 2025. This retrospective discusses that announcement rather than asserting a current deployment state. Check current Microsoft documentation for availability and tenant requirements.

Treat each agent as an operated service

Before a pilot grows, record its business purpose, accountable owner, data access, and expected actions. A demonstration is easy to approve when it has one user; the same workflow needs more explicit controls when it touches shared business information.

A concrete example

For an agent that prepares account briefings, identify which repositories it may read and where it may save results. Ask how a reviewer verifies the source material, what happens when an account owner leaves, and who notices a failed run. These are design questions for the pilot, not promises about product behavior.

Plan for retirement

Set a review date and a removal procedure when the agent is created. An inventory becomes meaningful when an owner can explain why access is still necessary and can remove it when the use case ends. Bring that evidence to leadership before proposing a wider rollout.
