See more details about an email

By default, each email you receive displays the email’s sender, recipients and date. If you want to see more details about a message—such as an email’s return and delivery paths, “Reply-to” field and content type—you can display its long header.

View long message headers

  1. Double-click a message to open it in a new window.

  2. Choose Show Long Headers from the Action pop-up menu in the toolbar.
