Microsoft Launches Copilot Agent Mode for Outlook, Inbox, and Calendar Management

Microsoft announced an upgrade to Copilot in Outlook that transforms the assistant into an autonomous agent capable of continuous inbox triage, follow-up drafting, dynamic rule creation, and proactive calendar management (resolving conflicts, negotiating meetings, blocking focus time, and generating agendas). The rollout via the Microsoft 365 Frontier program spans desktop, web, and mobile (with some calendar delegation limits), and the article highlights security and governance concerns—such as DLP interactions, access controls, audit logging, and an expanded attack surface—urging organizations to balance productivity gains with oversight.
