Copilot/Cowork Update

When will you be finished updating Copilot and carrying forward the different chats/discussions I've had with Copilot?

It appears that most of my chats after August 18, 2026, have been removed from history, yet I just opened it with the newer version. Almost like a System Restore, but I'm hoping most of that information hasn't disappeared.

Is there a way I can see what may not be carried forward, and why that wouldn't be the case?

I don't believe I've used any of the three major categories you've outlined on the Support Page that were going to be removed.

Also, currently there are no timestamps on when the "archive" of chats previously recorded.

    There is no published completion date for an individual account’s migration. The update rolls out gradually, and the time required varies based on the amount and type of content being moved.

    What is expected to carry forward:

    • Chats, images, and most other eligible Copilot content move to the updated Copilot app automatically.
    • If both the older Copilot experience and the Microsoft Copilot app were used with the same personal account, chat history and created content are merged into the single updated Copilot app.

    What does not carry forward or may be different:

    • Group Chat threads, messages, and content created in Group Chats will not carry forward after account updates that begin on August 18, 2026.
    • Podcasts is retired and no longer available after August 18, 2026.
    • Deep Research is retired and no longer available after August 18, 2026.
    • Some features may also be temporarily unavailable while the updated Copilot experience is rolling out.

    Based on the described symptoms, the missing history may still be in transit rather than deleted. The supported checks are:

    1. Verify the same sign-in method is being used as before: personal Microsoft account, or the same Continue with Google / Continue with Apple option.
    2. Close and reopen Copilot. On the web, refresh the page.
    3. Check for any in-app migration message. If shown, it may include a link to access previous chats while content is still moving.
    4. Allow more time and check again later, since migration timing varies.
    5. If multiple devices are involved, confirm the same account is signed in on each device and restart Copilot on each one.

    How to tell what may not be carried forward:

    • If the missing content was from Group Chat, it will not migrate and must be saved manually before the account update.
    • If the missing content was standard chat history, images, voice conversations, or most regular Copilot content, it is expected to move.
    • If Projects seem missing, they were renamed to Notebooks in the updated Copilot app and should appear in the left navigation pane.

    About the lack of timestamps in the archive view: the provided support content does not document timestamp behavior or a way to restore timestamps in archived chat history.
