Fix Microsoft Copilot Conversation History Disappearing After Reopening
Question details
The user is experiencing an issue where Microsoft Copilot fails to save or display previous conversation history after the application is closed and reopened.
- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Attempting to access previous AI chats after reopening the Copilot app.
- Observed behavior
- All previous conversation history is missing from the interface, even for chats that were created on the same day.
Ensure that you are actively logged into your Microsoft account, as Copilot conversation history will not sync or save if you are using the app as a guest.
Clear App Cache and Reinstall Copilot
Clearing temporary cache data and reinstalling the app often resolves underlying sync failures caused by corrupted local files or outdated versions.
If the mobile or desktop application encounters a caching error, it may fail to fetch your history from Microsoft's servers upon launch. A fresh installation forces the app to re-sync.
Navigate to your device's Settings, open the Apps or Application Manager, select Microsoft Copilot, and tap 'Clear Cache'.
If clearing the cache does not work, completely uninstall the Microsoft Copilot app from your device and restart your system.
Download the latest version of Microsoft Copilot from your official app store, launch it, and sign back in with your Microsoft credentials to trigger a fresh sync.
Check Copilot History via Web Browser
Accessing Copilot through a web browser helps determine if the issue is an isolated app glitch or a broader account sync problem.
Report to Microsoft Support
If the problem is due to server maintenance or a backend service update, escalating the issue to Microsoft Support is required.

Frequently Asked Questions
Are Microsoft Copilot conversations automatically saved?
Yes, Copilot conversations are saved to your account automatically, provided you are actively signed in with a Microsoft account. If you are using it unauthenticated, the chat history will be discarded when you close the session.
Does clearing the Copilot app cache delete my saved history?
No, your Copilot conversation history is stored securely on Microsoft's cloud servers, not in your device's local cache. Clearing the cache only removes temporary app files and forces a fresh sync from the cloud.
How can I manually export important Copilot conversations?
To ensure you do not lose important AI responses, you can use the 'Export' or 'Copy' buttons located below a specific Copilot answer to save the text directly into a Word document, PDF, or clipboard before closing the application.
Why does my Copilot web version show history but the app does not?
This discrepancy is typically caused by local app synchronization bugs, outdated app versions, or corrupted cache data on your device. Updating the app and logging out and back in usually forces the mobile version to match the web server.
