What it is

Microsoft 365 app: New Copilot Notebooks design in the Microsoft 365 Copilot App (iOS) is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: Launched.

What it does

Copilot Notebooks in the Microsoft 365 Copilot app (iOS) now lets users organize related chats, output creations, and references into a persistent AI workspace. Copilot uses the Notebook's accumulated context to ground responses, so work continues across sessions instead of starting over each time.

Why you should care

Board

Track as Horizon signal; decide whether it changes Wave 0 priority or stays on the watchlist.

CISO

Confirm identity, data access, and overshare exposure before enabling for broad cohorts.

CFO

Map licence or consumption impact to the frozen value case; avoid seat spray.

Adoption

Pilot with a named cohort and measure changed work, not vanity clicks.

Suggested action

Wave 0 first: Security → GRC → Cost & Value → Licence → Adoption. Decide: adopt for a named cohort, defer, or reject. If adopting, update licence and adoption plans in the same week.

Communication needed

  • Security: Assess exposure, Conditional Access, and agent/tool permissions.
  • GRC: Update AI/agent register and evidence path; confirm DPIA triggers if personal data is in scope.
  • FinOps: Forecast seat or credit impact; align to frozen value case.
  • Adoption: Plan cohort messaging, clinics, and success measures.
  • Comms: One story for board and staff — what changes, what does not, who owns risk.

Benefits

  • May improve productivity on a specific Microsoft 365 surface when permissions and data quality allow.
  • Roadmap visibility helps Horizon planning without guessing dates.

Risks

  • Status and dates change; treat MRC as directional, not a contract.
  • Enabling without Steady controls can amplify overshare or cost leakage.
