What Gets Removed
Data That Gets Deleted
This includes all prompts and responses you created. It clears activity across Microsoft 365 apps completely.

- Saved and shared prompts are not deleted.
- Pages and Notebooks are not removed here.
- Chats inside Pages and Notebooks stay stored.

Deleting Pages, Notebooks, and Files Separately
You must delete some content from its original location.
- Go to the Library to find and delete Pages.
- Deleting Pages removes chats stored inside.
- Open the navigation menu to delete Notebooks.
- Notebook deletion removes chats but keeps linked files.

Managing Instructions and Agents

Always delete pages, notebooks, and files separately when needed. This keeps your Copilot experience clean, simple, and secure.
