This is a MAJOR miss in the new Outlook (both web and app version). MS needs to bring back the option to create a rule that permits the "Reply" actions with specific message template/language. For example, I want to create a conditional rule that states any email coming from a specific sender should receive an auto-reply to sender with specific verbiage/message that I can create.
This was possible previously with Outlook - why would they take that away in the new Outlook??
