Powering Frontier Transformation with Copilot and Agents (Microsoft 365 Copilot Wave 3) The core focus is moving AI from simple assistance to “embedded agentic capabilities,” introducing Copilot Cowork and the Agent 365 control plane.
Real-time User Journey
The user journey in Wave 3 shifts from “single-turn” prompts to “multi-step” delegation:
- Trigger: A user starts with a complex, long-running request in Copilot Chat (e.g., “Analyze this quarter’s sales and draft a complete board presentation”).
- Reasoning: Copilot uses Work IQ to look across all relevant files, emails, and meetings to understand the context.
- Execution (Cowork): Instead of just giving an answer, Copilot breaks the request into steps. It can run for minutes or hours, updating spreadsheets with formulas and building PowerPoint slides with organizational brand kits.
- Transparency: The user sees “visible progress” and can steer, review, or stop the agent at any point.
- Finalization: The work is completed natively within Word, Excel, or PowerPoint, ready for final human approval.
Step-by-Step: How to Enable
As of the announcement, availability follows these tiers:
- Join the Frontier Program: Currently, advanced features like Copilot Cowork (the Anthropic-powered multi-step reasoning) are available through the Frontier Program (a research preview starting March 2026).
- Access General Availability (GA):
- Excel and Word: New agentic capabilities are already generally available within these apps.
- PowerPoint and Outlook: Features are rolling out through Spring 2026.
- Deploy Agent 365: IT Admins can enable the Agent 365 control plane via the Microsoft Admin Center starting May 1, 2026. This allows for the governance and security of all agents across the tenant.
