Copilot chat history partially missing after app update and migration

After updating the Microsoft Copilot app, my chat history was only partially migrated.

The updated app displayed a green confirmation that my chat history had been imported. However, approximately two-thirds of my projects, work plans, tables, and conversations from the last month are missing.

Some conversations were transferred, but they are incomplete or stop at an older point. I am signed in with the same personal Microsoft account that I used before the update.

During the migration, an age-restriction message appeared once, although the birth date on my Microsoft account is correct. That message later disappeared after account synchronization.

The previous Copilot app remains stuck on an “Install” screen. The updated app contains only part of my chat history.

Troubleshooting already completed:

  • Confirmed the correct Microsoft account
  • Confirmed the account birth date
  • Restarted the phone and the app
  • Cleared cache only
  • Did not clear app data
  • Did not uninstall the app

Device: Samsung Android phone

Country/region: Saudi Arabia

Issue started: 25 September 2026

Please escalate this issue to the appropriate Microsoft Copilot migration team. I need assistance restoring the missing server-side chats, projects, and conversation history without deleting or resetting the conversations that are still available.

    Hello احمد حدادي

    Thank you for reaching out and informed us about the situation with Copilot. I understand that the shared chat is missing and you can no longer able to access it anymore, before we proceed may I ask?

    • Which subscription do you currently have? (Microsoft 365 Personal, Family,..)
    • Is your account a personal or a work/school account?

    In case you're using a personal account with a Personal subscription, please try this step to access Copilot history:

    • Go to account.microsoft.com/privacy/copilot and click Export all activity history on each version of Copilot showing on the menu, then the chat history will be export to a CSV file and you should be able to view your shared conversation.

    At the moment there are no official statement from Microsoft about this issue but there are many other users who reported that they are experiencing the same issue as you are. If you're still unable to check the shared conversation, please reach out to Microsoft Support directly since as a Moderator we do not have any tools or access to Copilot directly to view, modify or recover any chats or history on other user's session. If you are using a personal account, please follow:

    • Go to Contact Us - Microsoft Support 
    • Select Copilot
    • Click Get Home Support
    • Type a brief description of your issue in the search box.
    • Click Get Help and select Contact Support below. 
    • Go to the Products and services tab and choose the appropriate product.
    • On the Category tab, choose the appropriate category or an alternative option.
    • Go to Confirm. Look for and select "Chat with a support agent in your web browser" (during business hours) if available. Explain your situation clearly.

    I hope this helps.
