explanation for non-techies**
Microsoft 365 Copilot is introducing a new feature that makes it easier for users to keep track of their conversations in Copilot Chat. Imagine you're having a conversation with a colleague in a meeting room, and you need to step out for a moment. When you return, you can pick up right where you left off without having to start the conversation over. This is similar to what the new session persistence feature does for Copilot Chat.
With this update, when you submit a prompt in Copilot Chat, a session entry is automatically created in the navigation pane. This means that if you need to navigate away from the chat to check an email or look at a document, you can return to the chat later and continue from where you left off. You won't lose any context or progress, much like bookmarking a page in a book so you can easily return to it later.
This enhancement is being rolled out globally starting December 12, 2025, and will be available to all users of Microsoft 365 Copilot Chat. There's no need for any administrative changes or actions, but it might be helpful to inform your helpdesk staff about this change and update any internal documentation that describes how Copilot Chat works.
Overall, this update is designed to improve the continuity and reliability of your conversations in Copilot Chat, making it easier to manage your workflow without interruptions.
