Updated October 30, 2025: We have updated the timeline. Thank you for your patience.
[Introduction]
We’re improving the reliability of Copilot chat by ensuring that conversations are preserved even when users navigate away from a chat. With this update, a session entry is created in the navigation pane as soon as a prompt is submitted. This allows users to return to the conversation later without losing context or progress.
This capability will be available to users with a Microsoft 365 Copilot Starter or Premium license. No additional license or add-on is required beyond a valid Microsoft 365 Copilot license.
This message is associated with Microsoft 365 Roadmap ID 500638.
[When this will happen:]
- Worldwide (General Availability): Rolling out from November 5, 2025 (previously October 27), to November 30, 2025 (previously October 31)
- GCC: Rolling out from November 19, 2025 (previously November 3), to November 30, 2025 (previously November 28)
