Org Email Box Sent Items

In Outlook, we have an Org Email account setup. Whenever someone replys from the box it is saved in the replier’s personel “sent items” which is normal. However, because of the way we work, we would like to have those replys from the Org Box be saved under the org boxes “sent items”.

I am unable to come up with an answer for a way to do this. Do anyone know? I believe I could setup a “rule” for each person with access, but that would require a ton of work and I’m hoping to save some time.

Thanks!!
