  • Hi park,

     

    Thank you for your post.

     

    As the error messages stated,  your IP address 216.32.180.186 was registered in SPAM Black IP List, that's why the recipient reject your emails. Once the IP address remove from the SPAM Black IP list, then the recipient can receive your emails.

     

    If this issue once occur, you may contact the recipient and let him to contact the administrator of their organization to check whether your IP address was blocked and then unblocked.

     

    If there are any questions when using Office 365 in the future, please feel free to post in forum. We are glad to assist you.

  • Hi Jolin Qiao.

    Thank you for your reply.

    You mentioned that the ip 216.32.180.186 is my IP, but it is not my IP.

    And I have searched this IP, I think this IP is Microsoft's IP.

    I have a question.

    I am using IP router in my company.

    According to you, if my IP is black list, how could my colleagues send messages to recipients?

    I don't understand these situation.

    Please post, I need your help.

    Thank you.
