asked on 

Office 365 hyrbid configuration.

Hi All,

We’re in a process to push office 365 hybrid configuration wizard to configure Exchange hybrid.

1. Is there any way we don’t directly expose our on-Premises Exchange servers to office 365?

2. Is there any requirement to open port 25 or port 80, 443 between office 365 servers and on-premises Exchange servers?

3. Can we make change into send and receive connectors after ruuning hybrid configuration wizard. It creates for us?
What we’re trying to achieve here is — Office 365 —> smart Host —> Exchange on-premise!

Thanks for taking your time to respond...
