  2. Hi,
    I’m planning to setup hybrid Office 365 with my exchange 2010 environment.
    fyi>EOP had already configured a few years ago with Office 365. so currently all incoming and outbound emails go thru Office 365.
    I was wondering whether I still require to do the Receiver and Sender Connector Configuration steps as part of the Wizard. do I skip this? as it’s already configured.
    Please advise.
