The chat history of Copilot has disappeared.

Did you try this ?

Forgive me but none of these answers work. I am using Windows 11 and MicrosoftEdge. Copilot is in Full Screen and on Neither side of the Screen is a history icon.

I see. You may follow these steps to view your chat history:

Open Copilot > Click on the Chat history button at the top of the Copilot side pane >
Click on the chat you wish to go back to under the "Recent activity"

I hope this helps!

i can't find this recent history icon also

my chat history yesterday has disappeared

For personal accounts:

On a desktop computer browser, it will be in the right side-panel, about halfway down the page (no icon needed).

If you are not signed it, you will not see history (at least I did not when I tried in a private browsing window).

On mobile; in the Copilot App, you click the 3 horizontal lines (“hamburger icon”) in the top left, and it will show previous chats about halfway down the screen.

If you are not signed it, I do not think you will see history.

For business accounts:

Certain security things your company puts in place prevents you from being able to have history. You can’t change this in settings either. Others have addressed this in their comments.

I recommend downloading or copy/pasting into a word doc once you get an answer you like.

Hope this helps!
