Intro

Microsoft’s late‑February 2026 roadmap drop is one of the densest in recent months, spanning Copilot, Teams, SharePoint, Purview, Edge, Outlook, and more. Across the board, the theme is clear: AI‑assisted workflows, deeper governance, and richer cross‑app experiences.

This post synthesizes the full roadmap updates provided by Microsoft structured as a readable update for admins, architects, and IT leaders.

Copilot: Deeper Integration, Better Grounding, and New Agent Capabilities

Copilot continues to expand across Microsoft 365, with a strong emphasis on Agent Mode, governance, and organizational customization.

    “Copilot Search can now match on a person’s department…”
