On March 9, Microsoft unveiled the third wave of updates for Microsoft 365 Copilot at the Frontier Transformation event, with the core change being a formal shift from an assistive tool to autonomous agents.
Copilot Cowork
The biggest change in the new Copilot isn't that it's smarter, but that it can work on its own.
Copilot Cowork can:
- Create work plans
- Reason across tools and files
- Drive workflows forward
- Keep moving even when you're not watching
Users can step in at any time to adjust direction. It can handle everything from calendar management to monthly budget reviews.
Multi-model strategy
Microsoft has explicitly stated that it is using both OpenAI and Anthropic's Claude models. As the largest investor in OpenAI, choosing not to lock into a single vendor at the product level is a noteworthy decision.
Agent 365
Launching on May 1, this is a unified management plane for enterprise AI agents. IT and security teams can monitor, govern, and manage all AI agents in one place.
For enterprise deployments, this centralized control capability may be more important than the agents themselves. No CTO wants dozens of different AI agents operating independently within the company.
Ecosystem and pricing
- M365 E7 (Frontier Suite): E5 + Copilot + Agent 365 bundled
- Support for MCP protocol and Apps SDK
- Integration with Adobe, Monday.com, Figma, and others
- Commercial pricing updated on July 1, with AI features moving from optional to foundational components
For developers, native MCP support means MCP Servers built for Claude can be reused directly in the Microsoft ecosystem. Interoperability is moving from theory to reality.
