Copilot Cowork lands in Frontier

This is Microsoft trying to turn Copilot into an execution layer, not just a text generator. The interesting part is the trust model: it can keep working in the background, but it still pauses for approval when actions matter, which is exactly the kind of autonomy enterprise buyers will tolerate.

• –Work IQ plus Outlook, Teams, Excel, SharePoint, and OneDrive gives Microsoft a real data-and-workflow moat, not just another model wrapper.
• –The Anthropic-powered angle signals a pragmatic multi-model strategy: Microsoft is optimizing for the best engine for the job, not a single-vendor story.
• –The strongest use cases are mundane but valuable: calendar cleanup, meeting packets, research memos, and launch planning are the kinds of repetitive workflows teams will actually pay to offload.
• –Frontier-only availability keeps this squarely in preview territory, so the real test is whether Microsoft can make this feel reliable enough to become a daily habit.
