our Excahnge ip address has been blocked by Microsoft's email servers for Namespace Mining. This was due to a spam attack on our server causing thousands of NDR's to be sent out in a matter of minutes.
I have since rectified this flaw on our server and am now trying to get our IP address un-blocked. However this is provong tp be very difficult. Simply, i cannot get through to anyone who knows what to do, or even what im talking about. I have spoken to about 25 different people at microsoft and all i get is " this is out of scope for me, please try...." and get passed onto someone else.
I have filled in this form 5 times
and only get a reply saying the IP is blocked and they require more information. They dont specify what more information they require. when i reply to the email, all i get is a reply saying the team will get back to you within 24 hours. this never happens. i eventually got an email back once saying that it was an outlook deliverability problem and had to fill in a form to contact them, the same form i had filled in in the first place.
has anyone else ever experienced this and how did you get your IP address un-blocked? does anyone know of any other avenue's or contact details that may help me to get this IP un-blocked? or are there any other suggestions.
