Microsoft Launches Copilot Cowork Cloud Agents With Anthropic Claude, Introduces $99 Microsoft 365 E7

The shift recasts Copilot as a governed, tenant‑secured automation platform built for large organizations.

Overview

  • Copilot Cowork, developed with Anthropic, adds multi‑step, autonomous task execution across Microsoft 365 and runs in the cloud inside a customer’s tenant under enterprise security controls, unlike Claude Cowork’s local device model.
  • The feature is in limited research preview and will reach Frontier early‑access participants later in March, with some usage included in the $30 M365 Copilot plan and additional capacity available for purchase.
  • Microsoft is making Anthropic’s latest Claude Sonnet models available across Copilot, signaling a multi‑model approach beyond prior exclusive use of OpenAI’s GPT models.
  • Agent 365, a governance and security control plane for AI agents, will be generally available May 1 at $15 per user per month; Microsoft reports tens of millions of agents registered in preview and more than 500,000 internal agents in use.
  • The new Microsoft 365 E7 bundle launches May 1 at $99 per user per month, combining E5, Copilot, Entra Suite and Agent 365, as Microsoft cites 160% year‑over‑year growth in paid Copilot seats and a tenfold increase in daily active usage.
