Exchange 2013 can't send email to external users such as xxx@outlook.com

    Question

  • Hi Experts,

    I have configured an Exchange server 2013 in an Azure virtual machine for test purpose. However, I can't send email to ANY external users such as xxx@outlook.com. I run the powershell  get-queue |fl. Here is the error. Any ideas?

  • Hi Jianggai,

    Does the issue only occur when sending to outlook.com domain ? If sending an email to other domains, such as a gmail user, is there the same issue?

    Please also check if your firewall or ISP block the outbound traffics on port 25, that would be a common cause.


    Best Regards,
