I am told they found the issue on our side and took the server out of rotation, so hopefully that clears up *THAT*. Still waiting on an explanation of the empty reply explanation.

I'm not looking for a golden ticket from anyone, but I wanted to see if fellow Deliverability professionals are seeing these kind of problems from Microsoft domains. We're just left scratching our heads as we try to fight these fires for our customers both the deliverability team and engineers. Has anyone else been having these problematic issues with Microsoft domains? Thanks, [Image removed by sender.
