One of my long-term Outlook gripes: Undo can catch a lot of things, but one of the things I use it most for is when I’ve changed my mind about deleting an email, so I want it back out of the Deleted Items. But it only works if you deleted from the folder, not from within the email itself, which then returns you to the folder. Would it be that hard for the logic to say “hey, he pressed undo, he must mean undo the last action” (well duh) “so I’ll undo the mail delete he just did.”
