Email sent was not received

I was sending an email to someone and I BCC'd another person. It said one email did not receive the email. Does that mean both people did not receive it or only one person did?

    Only the address listed in the non-delivery report (NDR) failed.

    If a message is sent to multiple recipients (To, Cc, or Bcc) and one address has a problem (for example, invalid address, mailbox full, server issue, or spam filtering), the NDR applies only to that specific recipient. The other valid recipients still receive the email.

    To confirm what happened, check the NDR details to see which address failed and why (for example, invalid email address, mailbox full, or spam filters).

    Dear @Sarah Gorde,

    Thank you for posting your question in the Microsoft Q&A forum.

    Based on your description, you sent an email to one person and BCC’d another, then saw a message indicating that one email was not delivered. You’re wondering whether this means only one recipient didn’t receive the email, or if both recipients missed it.

    When an email is sent to multiple recipients (including BCC), delivery is processed per recipient. If you receive a notification stating that one email was not delivered, it means only the specific recipient listed in the failure message did not receive the email. Delivery to the other recipient(s), including those in BCC, was not affected unless they are explicitly mentioned in the non‑delivery report (NDR).

    I hope information above meet your expectations, feel free to reach out if you have any other questions.
