Oct 2026 Migration: I Chats Missing from Standalone Copilot / Valuable Research Unavailable or Lost

Kate Peterson 0

With the Oct 2026 none of my chats from the standalone tool are displayed. Only Microsoft 356 Copilot chats are visible. Not having access to important research is causing great impact and anxiety.

I think this is a profile issue in that in the migration only one of the sources of my chats was carried over in the migration. I used the same user email for both. The one for Microsoft 365 used a Microsoft account. I think I used the same email but used Google to provide the authentication token (I am not sure as the UI is different and I would just click an option in the menu).

I tried a lot of things to bring the chats back. Rebooting, creating a new login alias to try to force a reload of the profile so it would reload from the underlying root directories from both sources, but nothing worked. I cleared caches of various kinds.

It seems this is a server-side issue. How long do we have to wait to get our chats back? I am really concerned that somehow they will be erased. Can they be ported manually?

Hello Kate Peterson,

I understand why this is concerning, especially when the missing conversations contain research and information that may be difficult to recreate.

Microsoft indicates that eligible personal Copilot chats should move automatically to the updated experience. If you originally accessed Copilot through Continue with Google, please make sure you use that same sign-in option, as a personal Copilot identity and a Microsoft 365 work or school account remain separate even when they appear to use the same email address.

Since you have already tried the common device and cache-related troubleshooting, this is unlikely to be something that can be resolved by creating another alias or making further local changes. Microsoft does not provide a fixed completion time for the migration, and there is no documented user-controlled method for manually importing the missing chats into another profile.

Please use Send feedback > Report a problem in Copilot and contact Microsoft Copilot Support. Describe the issue as a missing personal Copilot chat history after migration or a possible account-linking problem. Include the approximate date the chats disappeared, the original sign-in method, and confirmation that only the Microsoft 365 Copilot history is currently visible.

Please note that this is a user-to-user support forum. Community contributors cannot access account-linking records, check the server-side migration status, or restore missing conversations. Avoid posting email addresses, conversation links, chat IDs, or exported history publicly; provide those details only through the private Support channel.

I hope Microsoft Support can help determine whether the missing history is still associated with the original Copilot identity. Thank you so much for your understanding.

Thank you so very much for your detailed response. I was away working on other unrelated technical issues. I was so upset about this issue I wouldn't get anything done it I focused on it then.

No, my chats have not reappeared from my standalone account.

I have provided feedback through the application. I have drafted a letter that I am planning to open a support ticket, but I just have to figure out how to file the support ticket (sometimes their support menus as are very convoluted and go in circles). I am wondering if they will just close the ticket if I file it as I don't have a support contract like I would if it was my work computer, but I am filing it anyway.

I agree that it is a server-side problem. I need to hurry and they say on announcements that you have to login to your account by December. I have logged in many times, but I am worried they might erase by orphaned chats when they start erasing chats.

I personally think it may be because my username is the same for my Microsoft account (which my 365 version of CoPilot uses) and for my personal desktop version of CoPilot which uses the same id with a different password. Maybe if there is a conflict, they just choose the Microsoft one when they port the chats and have to do something special to get the other ones. That is why I used a new alias for my Microsoft account so it would be potentially forced to read the root directories and build the profile. I tried everything else that was mentioned here and elsewhere.

I will figure out how to do the support ticket today. This is so frustrating. I am really upset about how this migration has been handled.

Hello Kate Peterson,

Thank you for the detailed update. I completely understand why this migration has been so frustrating, especially when the missing conversations contain work that may be difficult or impossible to recreate.

You have already taken the appropriate step by submitting a report through the Copilot app. Your explanation about the two sign-in identities using the same visible email address but different authentication methods is also worth including in the support request. However, only Microsoft Support can review the account-linking and server-side migration records to determine whether the missing chats remain associated with the original personal Copilot identity.

At this point, I would avoid creating more aliases or making further sign-in changes. Keeping both account configurations unchanged may make it easier for Support to trace the original identity. In the ticket, please clearly state that:

The missing chats originated in standalone personal Copilot.

The original sign-in may have used Continue with Google.

Microsoft 365 Copilot uses a Microsoft account with the same visible email address.

Only the Microsoft 365 Copilot history is currently displayed.

The issue has already been reported through the Copilot app.

Although your concern about the chats becoming orphaned is understandable, I cannot confirm that Microsoft intends to erase them or that the December notice applies to the missing history in this particular situation. Including a screenshot or the exact wording of that notice in the private support request would help Support check how it applies to your account.

Please note that this is a user-to-user support forum, so contributors cannot inspect the migration status or restore the missing conversations directly. I hope the support team can trace the original Copilot identity and provide a clearer answer about whether the history is still recoverable. Thank you so much for your cooperation.

I am liking that there is a Get Help app that we can use where you can chat directly with a support agent. They are telling me I have to wait, but I am going to ask them more questions tomorrow. I had three separate char sources: 1) The standalone desktop app 2) chat that were created from a search and then selecting the Copilot option 3) Chats from Microsoft 365. They each had their own chat lists. I am not 100% sure the Google was involved in the Desktop app as I can't the old version of the desktop app however they all use the same id (as they all used my Google email as an id). I think I assumed I used Google or the lists in the Desktop app and the 365 app would be the same, but that is not true. They can all use the same Microsoft id and still maintain different lists.

I noticed in the Privacy app there are three categories of chats that are stored. The three categories may not map onto the three chats categories I used (as there are other origins for chats) but I am going to ask them in what category each of my chat sources will appear in once this is fixed. Knowing that might help me verify things when the fix is finally applied. It is not clear when they do appear if they will be sorted by date or just be appended to one another. Knowing that helps with verification that everything is there.

They did tell me this definitely would be fixed and my chats are not gone. I believe the engineer I spoke with was competent and sincere, but I am the type of person that won't believe it until I see it although they are probably right as at least that is their intent. In complex situations unfortunate things can happen though. I would have been more convinced if they looked directly at my records and configuration though and said,: "I can see your chats".

Oddly (perhaps since I am upset about this situation), I have always been a fan of Microsoft and like their products and as a stockholder pleased with their stock performance. I also believe users matter, not just innovating and make cool things but making sure new solutions are not pushed out to users before they are thoroughly tested. I wonder why these usecases were not tested or if they were not identified as use cases. Perhaps they made an earnest effort such that these unforeseen things could not have been anticipated. I am trying to still believe in their products...
