Microsoft 365 Copilot adds agent usage reports and governed search sources
Microsoft's 4 November release-note rollup adds an admin-center report for agent users, agents, publishers and user-agent pairs; lets administrators designate up to 100 SharePoint sites as authoritative Copilot Search sources; and links Excel chat responses directly to changed sheets, ranges, tables, charts and shapes.
Why it matters: The report makes shadow and low-adoption agents more visible, authoritative sources create an explicit ranking control for enterprise search, and Excel change links shorten the path from generated action to human review.
