Compiled from public Microsoft sources: the Microsoft 365 Roadmap, Learn release notes, and official blogs. Every item links to its source.
One note on dates, because it decides how to read several items above. A roadmap entry can be edited long after its feature shipped, and the public page shows only a “last modified” stamp, never what changed. Five entries resurfaced that way this week while their own availability dates are months old; each of those items opens by saying the entry was updated and gives the original date, rather than presenting the edit as fresh news. Roadmap items print the availability month Microsoft states on the entry itself, not the entry’s edit stamp.
What this edition set aside: an unannounced Microsoft agent product covered only by third parties this week, with no in-window first-party citation, and one Tech Community post whose publication date could not be confirmed. The admin controls above map to our free field guides on Copilot data scope and rollout.
