Hi Same issue here, we once again hit the dreaded: S3150 error last Friday.
Filled out the form - came back: we do not block any of your IP's listed. Replied once again with actual mail-logs showing the blocking. This morning got the surprising reply: We found and mitigated the issue. What we still would really like to find out is: What is the root cause of the S3150 issue? Is it Microsoft customers reporting spam mails they forward from their accounts on our platform to their Microsoft email addresses? Is it the few spam mails that are sent via phished accounts on our platform before our countermeasures manage to block the accounts? Is there anything we can do to prevent S3150 from happening repeatedly? > In my very limited sample size of 2, Microsoft's first reply is > automated and claims everything is peachy keen. However, if you reply > again your issue is actually reviewed, either by a bot or a human.
