We have had the same problems with Microsoft for some time now with a new block
we have, every IP is getting blocked for no reason, they say they have
unblocked them and they still treat received emails from those IP’s as spam.
They won’t unblock the whole subnet either.
Not sure what else you can do, and the problem is the customer sees it as your
problem when it’s Microsoft being over sensitive or something.

We've been having the same experience for months now. Not always, but way too
often.

Hi,
2 days ago one of our IPs started getting an AS3150 block when sending to
Hotmail/Outlook.
Which is very weird, as complaint rate and bounce rate are way below what
Outlook publishes as their official requirements.
After submitting their delivery support form, we get the automatic email saying
that the IP has been mitigated: "Our investigation has determined that the
above IP(s) qualify for mitigation. The block has been lifted, and the IP(s)
have been granted increased daily sending limits."
However, the IP still stays blocked! After replying to that email, we get a
copy-paste reply from Outlook.com support saying that "As previously stated,
your IP(s) do not qualify for mitigation at this time."
???
Alright, we repeat the process the next day, with the same results - initial
email says that the IP has been mitigated, that doesn't work and the IP is
still blocked, and Outlook.com support says that the IP is not eligible for
mitigation.
Asking to escalate to T3 did nothing.
Has someone else experienced this? What to do in this situation?
P.S. if anyone from Outlook/Hotmail are here, here is the ticket number:
SRX1410467394ID. I would greatly appreciate any help or insight into this.
Regards,
