What it is
Microsoft Copilot (Microsoft 365): Copilot Chat - Session Persistence Enhancement is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: Cancelled.
What it does
This feature ensures that conversations are preserved even when users navigate away from a session. As soon as a prompt is submitted, an entry is immediately created in the navigation pane’s session history. This allows users to leave the session and return later just as if they had never left. The update enhances continuity and reliability, making it easier to navigate without losing progress. Updated September 18, 2026: We are cancelling this Roadmap item at this time. We apologize for any inconvenience.
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. Log on Horizon; review with Counsel before tenant-wide change.
12 Panes: 03 Horizon · 08 Adoption
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.
