  • You can continue to route your inbound mail through the Barracuda with a hybrid configuration.  This way, nothing changes.  But that may not be the best for you since Exchange Online Protection does pretty much the same thing, so maybe it's best to take your on-premises devices and servers out of mail routing.

    Yes, the hybrid server needs its own IP address, and you should NOT configure hybrid mail flow between Exchange Online and your on-premises Exchange hybrid server to go through the Barracuda because it'll likely break everything or at the least be far more complicated to configure.
