![(Updated) Microsoft 365 Copilot: Session persistence enhancement for Copilot chat [MC1174856]](https://mwpro.co.uk/wp-content/uploads/2025/06/pexels-helenalopes-933964-1024x683.webp "(Updated) Microsoft 365 Copilot: Session persistence enhancement for Copilot chat [MC1174856] 1")
Updated December 11, 2025: We have updated the content and timelines. 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 Microsoft 365 Copilot Chat and Microsoft 365 Copilot users.
This message is associated with Microsoft 365 Roadmap ID 500638.
[When this will happen:]
- Worldwide (General Availability): Rolling out from December 12, 2025 (previously December 3), to January 12, 2026 (previously December 18, 2025)
- GCC: Rolling out from January 19, 2026 (previously January 3), to February 2, 2026 (previously January 30)
- GCC High: Rolling out from January 19, 2026 (previously January 3), to February 2, 2026 (previously January 30)
- DoD: Rolling out from January 19, 2026 (previously January 3), to February 2, 2026 (previously January 30)
[How this affects your organization:]
