Microsoft 365 Copilot has made individual tasks faster. What it has not done, until now, is take ownership of the work itself.
Copilot Cowork is built to change that. It brings natively governed, tenant-bound capability to Microsoft 365 that takes a user's intent and carries it through to completion across Outlook, Teams, Excel, Word, PowerPoint, and SharePoint without requiring manual coordination at every step.
The difference is that Cowork is not generating content for users to act on. It is taking action itself.
Copilot Cowork is bringing the technology platform that powers Claude Cowork to Microsoft 365 Copilot, integrated into Microsoft 365 through a partnership Microsoft has publicly confirmed. Claude was selected for its ability to handle:
Cowork uses Work IQ, Microsoft's contextual intelligence layer, to build a working picture of a user's environment before it acts. Work IQ tracks:
That context is what lets Cowork take high-level instructions and turns it into an actual plan. When a user submits something like "get me ready for the customer meeting" Cowork maps out the steps, surfaces the plan for approval, and then executes. It checks in when it needs clarification, but otherwise it handles the sequencing. Microsoft has built structured checkpoints and approval gates into the workflow, so users stay in control throughout.
Cowork is designed to eliminate the coordination overhead that typically spans multiple apps and manual handoffs.
Across all three scenarios, Cowork is focused on orchestration. It handles the coordination between applications, so the user does not have to.
No. Copilot Cowork does not require Microsoft 365 E7, but it is available with the E7 suite.
Cowork is included with Microsoft 365 Copilot, the same premium Copilot license organizations are already purchasing at ~$30 per user per month for enterprise and ~$20 for small business. Any organization with that license will get Cowork, regardless of whether they are on E7. It is currently available as a Frontier feature.
E7 is Microsoft's new frontier-tier SKU that bundles E5, Entra Suite, Microsoft 365 Copilot, and Agent 365 into a single license. Organizations running E7 gain access to Agent 365, which provides a governance and visibility layer for AI agents across the tenant, including Cowork activity.
Cowork runs inside an organization's Microsoft 365 tenant. It does not introduce a new security boundary because it does not need one. It inherits what is already in place:
Cowork can only see data the user is already authorized to access. Every action it takes is logged, audited, and covered by the same Microsoft Purview infrastructure that applies to user activity, including e-discovery and compliance reporting for regulated industries.
This is what separates Cowork from consumer and open-source agentic tools employees are already reaching for on their own. Those tools require external data connections and operates outside any governance framework the organization has built. Cowork does not leave the tenant.
As of March 2026, Cowork is available to organizations enrolled in Microsoft's Frontier program. Broad availability beyond Frontier has not yet been announced.
Frontier is the framework Microsoft uses to designate organizations actively adopting its most advanced AI capabilities. Enrolling involves enabling specific Frontier features inside the Microsoft 365 admin center, which is also what signals to Microsoft that the tenant is ready for early access. Organizations that want to get ahead of the broader rollout should:

Cowork introduces a category of AI behavior most Microsoft 365 environments have not had to account for before: AI that takes action on behalf of users. Before deployment, IT and security teams should confirm:
Cowork will work within whatever boundaries exist in the tenant. If those boundaries are not well defined, Cowork will reflect that. The teams that get the most value out of it will be the ones that treated the deployment as a governance exercise, not just a feature rollout.
Cowork is early in its rollout, and the full scope of what it will be able to do is still taking shape. What is already clear is that it represents a different kind of AI capability than anything Microsoft 365 has offered before.
For organizations already running Microsoft 365 Copilot, Cowork is coming whether they plan for it or not. The permissions, labels, and governance posture already in place will determine how much value it delivers and how safely it operates from day one.
