Hi Are those IPs on the same range ? We've seen cases were IP on the same pool but coming from different ranges received different treatment based on the reputation of other IPs in the vicinity.

I have been warming up new IPs for several weeks now. These IPs are part of the same pool and all send the exact same emails. After a few weeks, most of these IPs are not throttled anymore and can send whatever quantity of emails I need. However, two IPs (that send the exact same emails as the others) get throttling messages or even the "part of our block list" message (although on SNDS there is no mention that they are blocked). Outlook's support is of no use with pre-typed answers that can not give me an answer to this unusual situation : IPs that send exactly the same emails are being treated differently. Someone had the same issue before ? Is there a way to get in touch with someone from Microsoft that will actually take two minutes to try and understand the issue ? Thank you for your help. Regards, Mathieu.
