You should have seen the last of, “Transaction Failed” at about 1pm last Thursday, Feb 18th. If you’ve seen it since, we need to see the whole bounce.
As to the rest … I’d need to see some more explicit samples. “Redacted” is fine. But we need to know the banner you got when you connected, and as much of the transaction as you can share.

We've been trying to get to the root cause of why they could be creating so many false positives for our platform over the past few weeks.

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?
