A is incorrect: While copying and pasting works, Copilot Chat provides a built-in Edit in Outlook button when it detects email intent. This feature creates a pre-populated email draft directly in Outlook, eliminating the need for manual copy, paste, and formatting.

B is incorrect: Copilot Chat does not send emails directly on your behalf from the chat window. It offers an Edit in Outlook button to launch a draft in Outlook where you can review the content, add recipients, make edits, and send the email yourself.

C is incorrect: Retyping the prompt in Outlook duplicates effort and may not produce the same result since Draft with Copilot in Outlook uses different context. The Edit in Outlook button in Copilot Chat transfers the already-generated content directly into an email draft.

D is correct: When you use Copilot Chat in Work scope and signal intent to write an email, Copilot displays an Edit in Outlook button. Selecting it opens Outlook with a pre-populated draft including a subject line and body text, reducing friction when moving from insights to email composition.
