Microsoft Brings Anthropic’s Claude to Copilot With New ‘Copilot Cowork’ for Microsoft 365

Microsoft pitches a cloud‑hosted, enterprise‑governed agent that adds Anthropic models to Copilot to ease security worries, signaling a step away from sole reliance on OpenAI.

Overview

  • Copilot Cowork, developed with Anthropic and based on Claude Cowork, automates multi‑step tasks such as preparing meetings, generating presentations, updating spreadsheets, and coordinating emails.
  • Microsoft says Copilot Cowork runs within a customer’s Microsoft 365 tenant with enterprise data protections and Work IQ integration, contrasting with Anthropic’s local‑device approach.
  • The feature is in testing now with early access later in March, and some usage will be included in the $30‑per‑user‑per‑month Microsoft 365 Copilot plan with additional capacity sold separately.
  • Anthropic’s Claude Sonnet models are being made available to Microsoft 365 Copilot users, expanding model choice beyond earlier reliance on OpenAI’s GPT family.
  • Governance and packaging updates include Agent 365 general availability on May 1 at $15 per user per month and a new $99 Microsoft 365 E7 bundle that combines E5, Copilot, Agent 365, Entra and advanced security tools.
