How to set up emails replied from a shared mail box- The replied emails must land in the sent items of the shared mailbox.

Hi

We use Exchange 2017 and Outlook 2013 and there is a shared mail box called “NEWS” shared between 2 staff and  whenever they reply any email that is on the shared mail box the sent mail goes to their personal inbox sent items.

Is there any way to set up that when they reply any emails from the shared mail box, the replied email is on the shared mailbox sent items.

Any help would be great.
Thanks
