Is it possible to whitelist an IP address in my Exchange Online tenant if that IP address is banned (Blacklisted) in Exchange Online Protection system, I know that the IP address owner can go to https://sender.office.com and delist this address. I need to know if my tenant can whitelist that IP address eventough it is on EOP Banned list. 

 

550 5.7.606 Access denied, banned sending IP [PublicIP]. To request removal from this list please visit https://sender.office.com/ and follow the directions.

I don't think you can, because your IP is listed in MS database therefore it will still be picked. If i were you i would go the delisting option.
