Microsoft launches Scout, an always-on AI agent that automates tasks in Teams, email, and calendar for office workers.

Scout was announced at Microsoft's Build developer conference on Tuesday. It accesses work messages, calendar, and email inbox to automate tasks, reschedule meeting conflicts, and draft professional responses. The agent is built on top of OpenClaw, an AI tool from early 2026.

Scout runs continuously—even when the user is away from their desk. Users can set preferences (e.g., protecting dinnertime) and Scout will flag conflicting meetings and suggest rescheduling. The agent can also track promises and commitments across email and messages, then send reminders and draft follow-ups.

Microsoft is rolling out a desktop app version today to subscribers who have opted for 'frontier' feature access and an active GitHub Copilot subscription. A limited rollout is underway for Teams integration, with plans to expand access soon. Microsoft is also building administrator tools to track agent actions, addressing risks from prompt injection attacks (where bad actors confuse bots to reveal information).
