What happens when you delete your Microsoft 365 Copilot activity history
When you select Delete, a deletion request is sent to Microsoft. It might take some time before your Microsoft 365 Copilot activity history is fully deleted.
If an app is open when you select Delete, you might continue to see your previous activity history until you close the app. The next time you reopen that app and start using Copilot again, your activity history will be cleared. That means you’re starting over again with Copilot. Copilot doesn’t show any previous activities you had with it.
Any content that Copilot helped you with, and that you’ve saved in your file, won’t be removed when you select Delete. For example, if Copilot helped you with changes to your PowerPoint slides and you’ve saved those changes, those changes won’t be deleted.
