  • Hi,

    What information did you get from the Message Trace in Exchange admin center? Could you provide a screenshot about the delivery status and the message events? You can expand the message events to see if there is any error.

    Meanwhile, please try to add the domain to the user's safe send and domain list to see if it helps. If the user is having the issue on Outlook, please check he has enabled any Junk Email Options that could block or delete the emails.

    Regards,

    Alex Sun
