Microsoft to Roll Out New Outlook Features in May
Microsoft plans to roll out new Outlook features in May 2026, including calendar enhancements and expanded AI integrations. The web version will get a redesigned navigation bar that can surface team and manager calendars automatically and support third‑party accounts. Users will be able to select multiple calendars and non‑contiguous events using Shift/Ctrl.

Outlook feature becomes paid in September
Microsoft will remove the free Outlook feature "Meeting Insights" and replace it with a paid AI alternative. The rollout that removes Meeting Insights will begin in some regions mid‑August 2026 and be completed worldwide by early September 2026. The replacement, called "Prepare for this meeting," uses Microsoft 365 Copilot to access accessible emails and documents and summarize relevant information during meeting scheduling. The AI-driven replacement will require a Microsoft 365 subscription: single-user plans cost €99/year, family plans €129/year, and enterprise pricing is around €27 per user per month for Office apps plus Microsoft Copilot.
Microsoft Copilot Agent Mode Automates Outlook Inbox
Microsoft has added an "Agent Mode" to Copilot in Outlook, allowing the AI assistant to perform agentic inbox and calendar management on behalf of users. Announced by CEO Satya Nadella and described on the Outlook blog, the feature is available in Early Access through Microsoft’s Frontier program. Agent Mode can sort and prioritise emails, identify unanswered contacts, draft follow-ups, reschedule meetings to resolve conflicts and create agendas, all driven by natural-language prompts. Users can review the Copilot’s proposed actions, adjust settings or veto tasks. Microsoft positions the change as expanding agentic automation inside the Microsoft 365 ecosystem; the article notes Copilot Cowork and Claude-like agent inspirations as related developments.
