Summary: Microsoft is consolidating personal, work, and school access into an updated Copilot app while keeping personal and organizational data boundaries separate. The app adds direct access to Microsoft 365 apps, files, email, calendar, and cloud storage, but Microsoft is retiring consumer Deep Research, Podcasts, and Group Chat. Deep Research retirement began August 18; generated files move to OneDrive, and users must preserve Group Chat content that will not migrate.
Why it matters: Knowledge-work reliability includes tool continuity and record retention, not just answer quality. Users who depend on a research feature need an export plan, a replacement procedure, and clarity about which account owns each source and artifact. Microsoft says most data migrates, but retired features are handled differently and some functionality may be temporarily unavailable during rollout.
Original commentary: This is a practical lesson for books and workshops: design research workflows around portable sources, files, citations, and review checklists rather than around one product mode that may disappear.
