[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.
