What might be going on there is MSFT lifts the “block” but doesn’t change any thresholds/limits the IP is still susceptible to.
You may want to prompt the robots to give you the “new IP space” form to provide expected volumes from the IP, and see if MSFT will adjust thresholds on the IP. That has worked in the past for me, along with the mitigation. Brian Curry Email Deliverability Team Lead | Platform Services Merkle Inc.

"Block has been lifted" and then it's not.

Which is very weird, as complaint rate and bounce rate are way below what Outlook publishes as their official requirements. After submitting their delivery support form, we get the automatic email saying that the IP has been mitigated: "Our investigation has determined that the above IP(s) qualify for mitigation. The block has been lifted, and the IP(s) have been granted increased daily sending limits." However, the IP still stays blocked! After replying to that email, we get a copy-paste reply from Outlook.com support saying that "As previously stated, your IP(s) do not qualify for mitigation at this time." ??? Alright, we repeat the process the next day, with the same results - initial email says that the IP has been mitigated, that doesn't work and the IP is still blocked, and Outlook.com support says that the IP is not eligible for mitigation. Asking to escalate to T3 did nothing. Has someone else experienced this? What to do in this situation? P.S. if anyone from Outlook/Hotmail are here, here is the ticket number: SRX1410467394ID. I would greatly appreciate any help or insight into this.
