Is the primary the tenant.onmicrosoft.com one? If so, the issue is due to the default Email Address Policy in ExO, which stamps @tenant.onmicrosoft.com to each object. You cannot modify that policy, however you can change the default domain.

    tenant.onmicrosoft.com is no longer the "Default" tenant in Office 365 Admin Portal => Setup => Domains.

    Rather PrimaryDomain.com is the "Default" domain in O365 Admin Portal => Setup => Domains

    So, that ExO EAP shouldn't apply right?
