    I know the automatic 365 setup is behind the Paywall; But surley I can still set it up manually via the “Other SMTP” option??

    Many Thanks,
    Matt ??

    Hi @mazingmatt,

    Thanks for reaching out. On your error log posted above, I see the following message.

    We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

    Could you please get in touch with your email support with the above error log and they should be able to assist you further.

    In the meantime, you may configure an alternative mailer by following our documentation.

    I hope this helps.

    Thanks!
