I tried using Header Tools Improved to "Edit full source" to edit a received Gmail message.

The edited email was synced to Gmail web, but the date was changed to the time I edited the message, not the original received date, which makes it useless.


EDIT: "Edit Message" on Outlook desktop works fine with Gmail without changing the date on Gmail web.
