delist are not responding, removing our IP. We are green on evey email blacklist but microsoft bound our emails. RRS feed

  • Question

  • Guys

    Im getting slaughtered at work - nobody can email any office 365 or outlook.com users. 

    Microsoft servers bounce all email from our IP address, incorrectly, we are green on every email blacklist.

    We are a $1Billion dollar company.

    Ive sent ten requests in three days to be delisted, no response but an template email saying Microsoft will delist or contact us in 24 hours.

    This link shows we are not black listed on any other parties at all but Microsoft.


    Only Microsoft are bouncing our emails. Each time we receive bounces like this:


    Reason: Remote SMTP server has rejected address
      Diagnostic code: smtp;550 5.7.1 Service unavailable; Client host [] blocked using FBLW15; To request removal from this list


    When I email delist we get a response stating they will be back in touch in 24 hours, but there is never any response, but the below template, no follow up, still bouncing our emails stating our IP is the problem...

    How can I escalate this, over just emailing the same address to no response?
