I have an Exchange 2013 hybrid infrastructure with Office 365 (tenant 15....)
Mail flow is working well between in cloud mailbox and on-premise mailbox.
I have set the Outbound connector on my on-premise server to route mail through EOP (FOPE) on office 365:
mail.messaging.microsoft.com.
I get this delivery report every time:

A communication failure occurred during the delivery of this message.

I have activate for a while (FOPE) for my volume licenses users, but I want to use EOP on office 365 now.
thanks
