To use Copilot while drafting new emails in Outlook, open a new message and use the Copilot control inside the compose window.
For new Outlook or Outlook on the web:
- Select Home > New mail.
- In the blank email, select the Copilot icon from the toolbar, or select Draft with Copilot in the message area if it appears.
- Select Draft or Draft with Copilot.
- Enter the prompt for the email.
- Select Generate.
- Review the draft, then use options to adjust tone or length, regenerate, or keep the draft.
If Copilot is not showing in Outlook:
- Check with the IT admin, because access can depend on admin setup.
- In new Outlook and Outlook on the web, Draft with Copilot does not support emails composed in plain text. To use it, go to Settings > Mail > Compose and reply and select HTML.
If the issue is specifically the old inline prompt such as “Press Alt+I to draft with Copilot”, there is currently no known user-facing setting to turn that prompt on or off independently.
