Have you made any attempt to get your IP 'whitelisted' with Microsoft?
Several attempts. If you know of a decent contact I can pursue it further, but even after fighting with their usual ticket people and getting "mitigation" turned on for the sending IP things are still insta-spam-boxed. The MailOps list is filled with people in similar boats, and at least a few have given up and just relay to Microsoft as well.
