Inside Copilot Cowork: The Skills, Workflows and Enablement Steps

You’ve probably used Microsoft 365 Copilot to draft an email or clean up a slide. Copilot Cowork is a different animal. Hand it a brief, and it plans the work, moves across your M365 apps, and hands back a finished output.
I like to describe it less like a smart autocomplete and more like a capable teammate who already knows your files, your calendar, and your inbox. Below, we walk through what Cowork actually is, the skills it comes with, what the day-to-day workflow feels like, and what your admins need to do to turn it on.

What Copilot Cowork Is
At the risk of sounding reductive … Copilot Cowork actually does the work. You can describe what you need and it will break the brief into steps, working across your M365 apps, and delivering an output. It runs in the background while you focus on what only you can do. The result is a shift from “Copilot, help me write this” to “Copilot, go build this and show me when it’s ready.”
What Powers Copilot Cowork
Work IQ
It sits on top of Microsoft Graph, which means it already knows who you work with, how you communicate, and how your organization is structured. That context is the difference between output that fits your team and output that reads like it came from nowhere.
Anthropic
Anthropic’s Claude technology is integrated as a subprocessor into Microsoft 365 Copilot, providing the reasoning engine behind Cowork’s multi-step execution.

Meeting prep searches your files and assembles a briefing pack.
4 Steps to Enable Copilot Cowork
Turning Cowork on is mostly an administrative exercise. Three steps live in the Microsoft 365 Admin Center and are owned by a Global Admin; the final step is done by the end user.| Step | Where | Who |
|---|---|---|
| 1. Approve Anthropic Approve Anthropic as a subprocessor for the tenant. | M365 Admin Center → Copilot Settings → View all | Global Admin |
| 2. Enable the Frontier Program Find the Frontier program and opt the tenant in. | M365 Admin Center → Copilot (same view) | Global Admin |
| 3. Approve the Cowork Agent Approve Cowork for the organization, or for a pilot group. | M365 Admin Center → Agents | Global Admin |
| 4. User pins Cowork Open it once and pin it, from then on it lives in your agents overview. | Agent Store in Copilot | End User |
Note on Availability
Copilot Cowork and the Frontier program are rolling out across Microsoft 365 and the exact admin paths and naming may shift as Microsoft updates the experience. Confirm the current steps for your tenant before flipping it on broadly—and consider starting with a small pilot group.
