Office365 Connector

Hi All,

little confused with the office365 connector and Azure AD connector.

Our customer wants to create/manager mailbox in Office365. i was little confused, what connection do i have to do. in the sync service document it has mentioned create connection with Office365 to manage O365 object. so will be suitable in my case or i have to create connection to Azure AD as well?

if only Office365 connector can fulfill my requirement then how i can do the backsync? where and which attributes i have to use to store the office365 data?

customer is currently using AD sync tool to manage office 365 object.
