What happens when you delete your Copilot for Microsoft 365 interaction history

When you select Delete, a deletion request is sent to Microsoft. It might take some time before your Copilot for Microsoft 365 interaction history is fully deleted. 

If an app is open when you select Delete, you might continue to see your previous interaction history until you close the app. The next time you reopen that app and start using Copilot again, your interaction history will be cleared.

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.
