You have a Microsoft Exchange Online tenant that uses an email domain named contoso.com.
All incoming email messages route through an external third-party cloud filtering service named Filter1 to an incoming connector named Connector1.
You discover that the incoming messages contain headers that specify the source IP address as Filter1.
You need to ensure that incoming email messages contain headers that specify the source IP address of the original sender. The solution must prevent any changes to the external third-party cloud filtering service.
What should you do?
