Currently when you click an email address from a board it will pop open outlook - and the subject and “pulse address” will always be pulled from the original board that the item is in.
If that item is a mirror on another board - it will still populate the email from the original board.
I think its better if the mirror email pop-out populates from the CURRENT board - not the original/mirrored.
So it will show the subject of the Current board & use that pulse email too.
