sadly that is nothing new.
#Microsoft literally weaponizes it's position as "#TooBigToFail" #eMail #provider and comstantly make up excuses like "no #SPF / #DKIM / #DMARC records" when they themselves don't comply with it.
Consider involving all #regulators you can ranging from #FCC to @EU_Commission to @BNetzA to forve Microsoft to stop this shite...
