Changing the priority marking of sent emails

Having sent an email with high priority, I cannot change the priority marking. In Outlook, before filing old messages, if I had received a reply, I would remove the high priority marking. I cannot find how to change the priority markings in sent messages in eM Client. Any advice?

Unfortunately, it is not possible at the moment. If you want, you can create a new topic for this (Idea) and let people vote for it.
