Microsoft Launches Copilot Cowork: AI Agent That Works for You Across All of M365

Copilot Cowork — Agentification of M365

Microsoft has launched "Wave 3" of Microsoft 365 Copilot, with Copilot Cowork as the crown jewel — a cloud-based AI agent that executes multi-step tasks across all M365 apps. The agent was built in collaboration with Anthropic using Claude Cowork technology. Microsoft is simultaneously launching a new Enterprise package level ($99/user/month) called "Frontier Suite" that includes advanced AI and security features.

What Does This Mean?

This is the most concrete AI product launch from Microsoft in years — and it directly affects everyone already paying for M365.

My assessment

I advise several companies that already have M365 Copilot, and Cowork is a level up — it's the agentification of workflows, not just autocomplete. In an advisory board meeting last week, this was the topic: WHO will manage the agents and WHICH processes do we start with? For a CIO, this is a strategic decision that should be made in Q2 2026, not left to the IT department alone.
