Microsoft's anti-spam seems to be misfiring again but for once it is on the m365 paid customer. Seeing deferred messages like dsn=4.0.0, stat=Deferred: 451 4.7.500 Server busy. Please try again later from [38.124.232.13]. (S77714) [CO1NAM04FT003.eop-NAM04.prod.protection.outlook.com]
Anyone know how to open a ticket about this? Working for m365 customer(s) to open support tickets but is there a place for ISPs to let Microsoft know they have an issue?
