You might at least specify which workloads you are considering configuring in Hybrid.

That would be Exchange hybrid.

    So if you have AD FS and want to continue using it as authentication method for O365, you are tied in to AAD Connect anyway, and centrally managing your user objects via AD. Hybrid basically extends this to cover any Exchange related objects and attributes, effectively "extending" the on-premises organization to the cloud. Hybrid will offer the best experience during a migration, for both end users and admin, and if you decide to keep some mailboxes on-premises, it allows you to have a seamless experience, such that the users don't even notice when they are "talking" to a cloud user.

     

    On the con side, it requires some additional setup and maintenance.

      I'm looking more at we are currently in a hybrid environment and there is a request to look at removing Exchange on-premises and go to cloud only accounts. What happens when we remove Exchange completely from on-premises and use Cloud only accounts for Office 365?
