In Thunderbird, there's the option to "Edit As New...".
When selecting that option, I can edit the original message and send it like a new message.
How can I do the same thing in Outlook?
Note: This question is about the native Outlook Client (up to Outlook 2019). For the web client, aka "Outlook Web Access", "Outlook on the web", or "Outlook 365", see How do you "Edit As New" in Outlook Online? .
