Mail flow forwarding rule - NDR 554 5.7.1 Access Denied

    Question

  • Hi Guys,

    I have to forward emails sent to a shared mailbox called access.card@mydomain.com to an external email address mycompany@thirdparty.com.

    I have created a mail flow rule to forward all emails sent to that address to the external address I need. Cool. This is fine.

    The problem now is that I'm getting NDR 554 5.7.1 Access Denied when sending emails to access.card.

    Do you guys know how to help me?

    Thanks,

  • Can you please elaborate the mail flow rule?

    It should be done by creating a server side rule on user mailbox which should says any email receied by access.card@mydomain.com to external address (you can setup a mail contact in exchange point to external contact) and try after that?

    Thanks

  • Hello,

    To fix your issue, I want to confirm:
    1. Does this issue occur on internal user send a message to access.card, or others as well?
    2. Is this issue only arise after configure e-mail forwarding?
    3. Is it a contact with "mycompany@thirdparty.com", and also use inbox rule or transport rule to configure e-mail forwarding?

    If it arise after e-mail forwarding setup, please double check the e-mail forwarding settings (rule settings).

    By the way, we can use ForwardingSMTPAddress or ForwardingAddress with Set-Mailbox to configure e-mail forwarding.
    More details, for your reference:
