Deleted mail cannot be recovered from trash
Since installing Catalina, I cannot recover a mail message after it is deleted. Before Catalina, I was always able to go the Undo" button in the menu and the message would return to the inbox, junk, etc., but now it seems to be permanently deleted as soon as you hit the "delete" button -- it cannot be found in the trash, either, because there seems to be no way to view the trash. Any answers here???? Thanks.
