IP Delist not working - Microsoft Community

-

greetings everyone.

i bought hosting yesterday , wanted set mail , start using before getting website up. saw e-mail banned/blacklisted. following error message recieve:

smtp error remote mail server after rcpt to:mail address
    550 5.7.606 access denied, banned sending ip [xx.xxx.xx.xx]. request removal list please visit https://sender.office.com/ and follow directions. more information please go  http://go.microsoft.com/fwlink/?linkid=526655 (as16012609) 

my hosting provider drxxxxxxxxxxxxxxxxg.net <modified moderator due privacy>

i got no e-mail after using sender.office.com portal, , unable resolve issue. recommended course of action?

hi ivakkukic,

if did not receive email sent delisting portal, check spam or junk email folders. if still can’t locate email , have problem submit request using office 365 delist portal then, please contact office 365 admin/customer you're trying email using method (e.g. phone/personal email) , ask them contact microsoft support , open support ticket on behalf. 

in cases, legal reasons, microsoft support communicate directly sender owns ip space being blocked. however, non-customers typically can't open support tickets.

reference: services non-customers sending mail office 365

time , understanding highly appreciated.

best regards,
shyamal
