Microsoft now adds Agent Mode and Office Agent to Microsoft 365 Copilot. Agent Mode works inside Excel and Word to execute multi-step tasks, validate results, and let you steer the process. In Excel, it picks formulas, builds visuals, and revises automatically. In Word, it generates, polishes, and refines documents via conversational prompts. Office Agent works inside Copilot chat: you ask for a presentation or report, it researches, drafts slides/documents, and lets you iterate. Rollout begins now via Microsoft’s Frontier program in the U.S., with web versions first and desktop coming later.
