3. Review, Edit, or Regenerate the Draft
Inside the draft itself you will be able to review the AI-generated reply and ask Copilot to reword it further. You can make it more formal, concise, or friendly using built-in options. Ask Copilot for further adjustments or clarify the tone you want. Once you are happy with your answer, you are done and you can send the email!
