    Hello Matt,

    Thanks for your post.

    If the recipient is an Office 365 account, I suggest you let him add you email address to the safe sender and recipients lists first. From the NDR(non-delivery report), the issue occurs because your domain has a SPF record that doesn’t include the IP address that you are sending emails from. Please follow the instructions below to check the SPF record:

    1 . Press Win + R, type nslookup and click OK.

    2 . Type set type=txt, press Enter.

    3 . Type your domain and press Enter. Then capture a screenshot and upload it via private message.

    To further investigating to this issue, I need to collect some information:

    1 . Please upload the full NDR(non-delivery report) via private message.

    2 . May I know if the recipient is an Office 365 account?

    To protect your privacy, I have sent you a private message to collect them. Please click on the link below to access your Private Message : https://answers.microsoft.com/en-us/privatemessage/inbox
