Did you make any headway this issue? We've been having the same issues since

Hi,
On Apr 06 we detected that 28 IPs were blocked in Outlook.com, all with the
following error:
550 5.7.1 Unfortunately, messages from [185.103.9.41] weren't sent. Please
contact your Internet service provider since part of their network is on our
block list (S3150).
Question for each of you: Who is your service provider - i.e. from whom did you
get the IP addresses?
Anne
Hi Anne,
The IP addresses (for us) are from Hetzner and SwissHost.
