(Updated) Microsoft 365 Copilot: Session persistence enhancement for Copilot chat [MC1174856]

Message ID: MC1174856 (Updated)

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)
• GCC High: Rolling out from November 26, 2025 (previously November 10), to November 30, 2025 (previously November 28
• DoD: Rolling out from November 19, 2025 (previously November 10), to November 30, 2025 (previously November 28)

[How this affects your organization:]

Who is affected: All users of Microsoft Copilot (Microsoft 365) in commercial, GCC, GCC High, and DoD environments with a valid Microsoft 365 Copilot Starter or Premium license.

• A session entry will now appear in the navigation pane immediately after a prompt is submitted.
• Users can navigate away from a chat and return later without losing the conversation.
