Copilot Cowork Is Live – The AI That Actually Takes Action (Admin Setup + Real Demos)

Microsoft 365 Copilot Cowork is officially available in the Frontier program as of April 2026 – and it's a completely different kind of AI experience. This isn't Copilot answering questions. This is Copilot actually DOING the work: sending emails, building decks, scheduling meetings, managing your calendar, and more – all while you watch it execute step by step. In this video I walk you through everything you need to know as an IT admin and power user: • What Copilot Cowork actually is (and how it's different from regular Copilot) • Real-world demos that show what it can actually do • What Cowork CANNOT do (honest limitations) • How admins enable or disable it in the Microsoft 365 Admin Center • The 13 built-in Skills – what they are and how to create your own custom ones • Keyboard shortcuts and power-user tips • Multi-model architecture: Anthropic (Sonnet/Opus) default, model picker in UI, model-agnostic design • Cloud-native: isolated sandboxes per session — no local machine impact 🔑 Admin Center: [admin.microsoft.com](http://admin.microsoft.com/) → Copilot → Agents → All agents → Cowork (availability: all users, specific groups, or blocked) ⚠️ If Cowork isn't visible in Agent management, ensure admin is enrolled in Frontier (Copilot → Settings → Frontier) 🛠️ Built-in Skills (13): Word, Excel, PowerPoint, PDF, Email, Scheduling, Calendar Management, Meetings, Daily Briefing, Enterprise Search, Communications, Deep Research, Adaptive Cards 📁 Custom Skills: [SKILL.md](http://skill.md/) with YAML frontmatter (name + description) + markdown instructions in OneDrive → /Documents/Cowork/Skills/[skill-name]/ (up to 20 skills, 1 MB each) 💻 Available: Browser ([m365.cloud.microsoft](http://m365.cloud.microsoft/)), Outlook, Teams, desktop app (Windows/Mac) — no mobile yet Helpful Links: Microsoft Blog Post: https://www.microsoft.com/en-us/micro...
