According to Satya Nadella on X, Microsoft launched Copilot Cowork to convert natural language tasks into executable multi-step plans across Microsoft 365 apps, operating within existing security and governance boundaries (source: Satya Nadella). As reported by Microsoft via its official X announcement, Cowork orchestrates actions across files and apps grounded in enterprise data, signaling a shift from chat-style assistance to agentic workflow automation for knowledge workers (source: Satya Nadella). For businesses, this positions Copilot as a task automation layer spanning Outlook, Teams, Word, Excel, and SharePoint, with potential ROI from reduced context switching, faster handoffs, and consistent compliance controls within M365 (source: Satya Nadella).
