co-pilot chat history disappearred

Hi @Lu

I’m sorry to hear that your Copilot chat history from before April 27, 2026 has disappeared, especially since you need those conversations for work.

First, please make sure you are signed in with the same account and sign-in method you originally used with Copilot. If you used Google or Apple to sign in, select Continue with Google or Continue with Apple, rather than signing in as a Microsoft account. You can also check the Chats list in Copilot on the web, desktop app, and mobile app to see whether the history appears on another platform.

If the conversations remain missing, please contact Microsoft Support:

• Select Show expanded list of products.
• Select Copilot > Get Home support.
• Enter live chat, then select Get Help > Contact Support.
• Sign in with the affected account. If you cannot sign in, use another Microsoft account to view the available support options.
• In the Support Assistant, enter Talk to a live chat agent, then select Contact Support.
• Under Products & Services, select Copilot, then choose Chat with a support agent in your web browser.

Please note that this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance regarding reported issues, requests, or ideas.

Thank you for your understanding.
