Microsoft AI Updates: May 15, 2026

1. Copilot in Microsoft Edge gets multi-tab reasoning, long-term memory, and mobile availability

Microsoft. Microsoft began rolling out a major Edge update that lets Copilot reason across all open tabs to deliver side-by-side comparisons, adds long-term memory so Copilot can recall and reference prior chats, and brings Copilot experiences to the Edge mobile apps on iOS 18+ and Android 14+ for the first time. The release also broadens Journeys, ships a Study and Learn mode with quizzes and flashcards, and retires the separate Copilot Mode in favor of features built directly into the browser; it is available on Windows 11 24H2+ and macOS 15.

2. Workday Sana Self-Service Agent goes GA inside Microsoft 365 Copilot

Microsoft. Workday made its Sana Self-Service Agent generally available inside Microsoft 365 Copilot, letting employees check PTO balances, file expenses, query equity vesting schedules, look up policies, and trigger Workday HR and finance actions in natural language without leaving Copilot. The agent connects to Workday’s existing approvals and policies, ships as a Microsoft Marketplace app with no separate login or extra licensing, and extends to manager workflows like bulk timesheet approvals and performance review starts.

3. Microsoft Marketplace May 14 drop adds 66 new offers, heavy on agentic AI

Microsoft. Microsoft’s Marketplace team published its release recap certifying 66 new partner offers, with a notable concentration of AI agents and Copilot extensions including AI Document Processor for UK Healthcare, ETIYA Agentic AI, ETIYA Conversational AI Agent, ETIYA Digital Interaction Management, and the Mavvrik AI cost governance platform. The cadence reinforces Microsoft’s pitch that Marketplace is becoming the transactable channel for Copilot- and Foundry-adjacent ISV solutions rather than a static directory. Source
