    Hi Jonathan Bell2,

    Good day!

    Thank you for bringing the email delivery issue to our attention. I sincerely apologize for the inconvenience this has caused you and fully understand how frustrating such disruptions can be, especially when trying to communicate effectively. Please rest assured that we are here to assist you and resolve this matter as quickly as possible.

    From the details you’ve shared, it seems the error message indicates that the recipient’s mailbox is full and cannot accept messages at this time. The specific error code you mentioned is 554 5.2.2 (mailbox full), which typically points to a storage quota issue on the recipient’s side.

    To help us investigate further, could you kindly confirm a few details?

    1. What type of account are you using? Is it a Microsoft work/school account or a personal account like outlook.com/live.com/hotmail.com?
    2. Is it hosted in an on-premises, pure cloud, or hybrid environment?
    3. Are you seeing error messages similar to the following?
      • The recipient's mailbox is full and can't accept messages now. Please try resending this message later or contact the recipient directly.
      • Diagnostic information for administrators: Remote Server returned '554 5.2.2 mailbox full; STOREDRV.Deliver.Exception:QuotaExceededException .MapiExceptionQuotaExceeded'

    If this is the case, I recommend referring to this article for guidance: Cannot send mail: mailbox full. It provides steps to address the issue, such as clearing space in the recipient’s mailbox or adjusting mailbox quotas.

    However, if the issue persists or the error message differs, could you please provide the full non-delivery report (NDR) for further investigation? This will help us pinpoint the root cause and take the necessary steps to resolve it.

    Once again, I apologize for the inconvenience this has caused and appreciate your patience as we work to resolve this matter. Please don’t hesitate to reach out if you have any additional questions or need further assistance.

    Looking forward to your response.

    Warm regards,

    Luckie Shi
