Reply to Email for SO/PO

Hello,

We are new to Zoho Books and running into an issue. Our support@ email is our integration user. When our team is sending out PO/SO's we are updating the sender email, but for some reason many of our responses are coming back to our support@ email instead of being directed to the sender of the SO/PO as we would like.

I can't seem to find any specific reply to preferences in the email settings of Books.

Does anyone have an idea of what we're doing wrong and how to resolve?
