I have an all cloud email environment in O365 but an on-premises Active Directory environment. We must introduce Azure AD Connect to get the two environment aligned. I know what I need to do to soft match the O365 accounts with the on-premise AD accounts. I also know I need at least an Exchange Management Tools server to management my users that will now be sourced on-premises. What I do not know is if I need to run the Hybrid Configuration Wizard. There is absolutely no mail currently on-premises and there never will be. Do I still need to run HCW in this situation? Thanks.
