Copilot chat disappeared

Question

Copilot chat disappeared

Brennan, Amanda 0

My phone Copilot sessions used to rely on my Google identity token and has all my chat history. My web browser Copilot now forces me into a personal Microsoft account using that exact same Gmail address, which is showing up without my chat history. I am experiencing a backend server-side migration conflict. I need an escalation to have my Google account history manually synced or cleared to finish merging into my Microsoft account profile.

Hi Brennan, Amanda,

Thank you for confirming that the suggested steps did not resolve the issue.

Could you please clarify whether the missing conversations are still visible in the Copilot mobile app when you use the original Google sign-in, or whether they have disappeared there as well? This will help determine whether the history is still associated with the original sign-in session or is unavailable across both experiences.

Microsoft indicates that eligible chat history from linked personal sign-ins should be moved automatically to the updated Copilot experience. However, there is no user-accessible option to manually force a sync or merge the histories. Since the sign-in checks have already failed, this likely requires an account-specific investigation that cannot be performed through this user-to-user forum.

Please contact Microsoft Support and describe the issue as a Copilot chat-history migration or account-linking issue. If the Support Assistant appears, enter:“I need a live support agent to investigate missing Copilot chat history.”

Please avoid sharing conversation links or chat IDs publicly. If you have them, provide them only through the private support session. Thank you so much for your understanding.

Google sign-in is not possible - I am forced into the Microsoft live login.

Hi Brennan, Amanda,

Thank you for clarifying. Since Copilot no longer offers Continue with Google and redirects you automatically to the Microsoft Live sign-in page, repeating the previous sign-in steps would not resolve the issue.

Please note that this is a user-to-user support forum, so moderators and contributors cannot access account migration records or restore missing Copilot conversations from the back-end system.

Please report the issue in Copilot through … > Send feedback > Report a problem, clearly stating that your previous chats were created using Google sign-in but that Copilot now forces Microsoft Live sign-in. You may also contact Microsoft Copilot Support and use this prompt if the Support Assistant appears: “I need to connect to a live support agent.”

Please share any old chat links or IDs only in the private support session. Thank you so much for your cooperation.

I have been dealing with this same issue since the transition. And I have contacted Tier-1 support (India) 3 times (cases) without being able to get them to escalate identity‑migration failures. Tier‑1 cannot access Copilot backend logs. Tier‑1 cannot trigger identity merges. Tier‑1 cannot fix Google→Microsoft migration conflicts. Tier‑1 cannot reach the Copilot engineering team or at least have not put my request through. Tier‑1 will loop you through scripts again. Tier‑1 will ask for device access or password resets. Tier‑1 will close the case without resolution. I do not know how many similar cases of this there are but it would be helpful to know that Microsoft recognizes this problem at a level that is capable of working on it with some sort of timeframe.

Hi Mark Reed,

Thank you for sharing these details. I understand how frustrating it must be to contact Support several times, repeat the same troubleshooting steps, and still have the cases closed without the migration issue being resolved.

At present, I am unable to confirm from the information publicly available whether Microsoft has formally classified this as a broader service incident or provide a timeframe for a resolution. This user-to-user forum also cannot review support cases, access Copilot back-end records, or initiate an internal escalation.

If you still have the previous case numbers, please contact Microsoft Copilot Support again and provide all of them together. Ask the support representative to review the earlier cases as a Copilot account migration or account-linking issue involving Google and Microsoft sign-in, rather than as a device-access or password issue.

Please also submit a report from Copilot through … > Send feedback > Report a problem. Include the previous case numbers, the approximate date the issue began, the original sign-in method, the devices affected, and screenshots showing the missing history. This creates a product report containing the diagnostic details available from your Copilot session.

While I cannot guarantee an escalation or recovery of the missing conversations, your detailed report is valuable and may help Microsoft identify how many users are experiencing this migration behavior.

Thank you again for taking the time to share your experience with the community.

... well something happened with this the morning of Oct 21. In opening both this desktop version of CoPilot and the browser version of CoPilot they both went through a chat update and it appears both versions have merged into one. All chats that existed in each separately are now merged into one and are showing my Microsoft Avatar. My google sign in has dissappeared but all chats have migrated together. In addition when I try to open the Legacy app on my phone it is forcing me to install the new Copilot app. I now see in both instances on the desktop all my chat history. Evidence suggests that a full migration has been completed and I am so thankful! I hope others are seeing this happen for them!

Hi Mark Reed,

Thank you for coming back and sharing this positive update. I’m glad to hear that the migration appears to have completed and that your full chat history is now visible in both the Copilot desktop app and the browser version.

Your detailed explanation will also be helpful and reassuring to other users who may be experiencing the same transition. While the timing may vary between accounts, your experience shows that the missing chats were eventually brought together under the Microsoft account rather than being permanently lost.

Thank you again for keeping the community informed. I’m pleased that you can now access your full chat history!
