All emails from one of our domains are marked as spam ONLY by Exchange Online

We are running Exchange on-prem with two accepted domains. Both domains follow the same Exchange mailflow rules, outbound mailflow and both have correct SPF records. One of these two domain's emails gets marked as spam with SCL:5 and one does not. This domain's emails are ONLY marked as spam when sending to Exchange Online mailboxes. I can not find a single difference between how the two domains are configured nor why one is marked as spam and one is not. How do I get the domain not marked as spam? I'm lost as where to go next.
