Microsoft Copilot Cowork Becomes Generally Available Worldwide
- Microsoft made Copilot Cowork generally available worldwide on 16 June 2026, after three months of preview in its Frontier program (30 March to 16 June)[1][5]
- More than half of the Fortune 500 used it during the preview, along with Accenture, Avanade, Capital Group, Koch, Ooredoo Qatar and Zurich Insurance; Microsoft calls it the fastest-growing feature in Frontier's history[1][4]
- It needs a Microsoft 365 Copilot user licence and is billed on usage in Copilot Credits; billing began on launch day, with tenants that used it in Frontier not billed until 1 July 2026[1][5]
- Cowork is off by default: admins decide when to enable it and for whom, and can set spending limits and alerts at tenant, group and user level[1]
- Microsoft has kept adding features since launch, including building and sharing apps inside Cowork and plugins on the mobile app[2][6]
Notable features
- An agentic system for complex, long-running, multi-tool tasks: the user defines the work and Cowork runs it end to end and returns a finished result rather than a draft[1][3]
- Runs in the cloud, so tasks keep going with the laptop off, grounded in the organisation's data through Work IQ and inside the Microsoft 365 trust boundary[1][4]
- Multi-model: Microsoft's announcement says it launched on Anthropic's Opus 4.8 and Sonnet 4.6, with GPT 5.5 in Frontier and Microsoft's own lower-cost Cowork 1 model coming[1][5]; Microsoft Learn's changelog lists Claude Sonnet 5 replacing Sonnet 4.6 at general availability, and GPT 6 Astra and Claude Fable 5.1 added in September 2026[2]
- Pay-as-you-go at $0.01 per Copilot Credit, each task priced from model use, context retrieval, tool calls and runtime; Microsoft's own tests put it 30-40% cheaper per prompt than Claude Cowork with its Microsoft 365 connector[1]
- Partner plugins at launch from Enosix, Harvey, LSEG, Miro, monday.com, Moody's, Morningstar, S&P Global Energy and TeamsMaestro, with Adobe, Atlassian, Box, Canva and Databricks coming[1][3]
- Can work in web pages through a local Edge browser with the user's sign-ins and the organisation's policies, in Frontier at launch and generally available to all Copilot tenants from August 2026[1][2]
- Its prompts, responses and generated files fall under existing Microsoft 365 controls, including the audit log, eDiscovery and data lifecycle management[1]
