Release Notes for Microsoft 365 Copilot: updates released between July 01-15, 2026
A general roundup of admin-facing Copilot changes — agent publishing to the Agent Store, an org-wide prompt gallery, MCP agent access inside Office apps, brand kit generation, and connector permission handling. Most useful to IT/Copilot admins wanting one view of what changed, rather than something typical end users need to act on.
