Marking an email Done does not move it, so nothing has to be recovered. The message is still in your inbox, marked read and tagged as handled. Clearing that status takes one tap, either way:
- Open the email and mark it Undone.
- Find it in the Done column of your Later Board and mark it Undone from there.
The Done tag is removed and the email leaves the Done column of the Later Board, exactly as it was before.
