    Hi @ Handian Sudianto,

    If a message fails DMARC inspection, you can specify the action to reject the message for the sender's DMARC policy in the anti-phishing policy.

    For more information, please refer to the following link:

    Anti-phishing policies | Microsoft Learn

    Configure anti-phishing policies in EOP | Microsoft Learn

    In addition, mail flow rules can also reject messages that fail DMARC checks, you can refer to the following screenshot settings:
