Compiled from public Microsoft sources: the Microsoft 365 Roadmap, Learn release notes, and official blogs. Every item links to its source.
One note on what counts as news here. Thirty-five items from earlier editions were left out because their status has not changed. Six items in this edition carry a status change and open with the labeled change, and two open with a note that a public roadmap entry now confirms them. The Microsoft 365 Copilot release notes on Learn published no new batch in the window; the newest batch is dated 25 August 2026, so nothing in this edition rests on release notes.
What this edition set aside: a conference promotion for ESPC 2026 in Amsterdam, a repost of the 10 September app-building announcement already covered last week, the undated “What’s new” entries on the Frontier features page, and a Copilot Studio blog teaser about an analysis of 40,000 agents with no dated post behind it. The admin controls above map to our free field guides on Copilot data scope and rollout.
