    Hi Maxis,

    Please provide more concrete information about your setup and emailflow.

    Troubleshooting action plan:
    - Check your smtp relay server logs
    - Check your Symantec email gateway logs
    - Check the Exchange Online logs (admin.exchange.microsoft.com > Mail flow > Message trace > Search > Message events)

    Also note these Exchange Online limits:

      hi, the EOP is not applicalbe here as the application forward the email > on-prem bulk mail server > on-prem Symantec Mail Gateway > External .
      honestly, i cant find any relevant logs in smtp relay server. Symantec gateway logs i have to ask other team.
