To have all officers and sender receive responses to an email, the setting for “Recipient of replies to officer email list emails” should be set to “All Officers & Sender”. Make sure your officers know what the setting is if you change it. Just pressing reply will actually reply to all in the group.
Other members can send emails to the officer mailing list. Only officers will receive the emails sent to officers
It sounds as though you might need to create a Custom Group of the specific Members and Officers you want for your purpose, and set up the recipients of replies to emails to custom groups appropriately.
