You have a DMARC record, thus the policy was triggered. See How Microsoft 365 handles inbound email that fails DMARC for more. | |

Thank you for the detailed answer. After reading through the link and everything you explained i have one remaining question about this part: dkim=pass (signature was verified) (So this part only checks if the Sender has a verified DKIM or not - it doesn't matter what Domain this DKIM represents.) header.d=myprivategym.ae;dmarc=fail action=quarantine (The dmarc entry checks for the domain alignment - if there was no dmarc record the DKIM message above would have no impact how the mails were marked. I will check with Microsoft how we can manage those kind of mails.
