Exchange 2016 is the latest version of Microsoft’s on-premise email platform.
Migrating to Office 365 can be done via the Hybrid Configuration Wizard (HCW) or via a cut-over migration.
The Hybrid setup, once setup, provides the least risk, more flexible, solution.
Exchange 2016 to Office 365 Hybrid Migration
If using the Hybrid approach, my recommendation is to keep your mail transport via on-premise Exchange, for inbound and outbound email. This is under one of the Advanced options in the HCW. Setting up dedicated Hybrid servers is also a wise move, and means you do not have to change any on-premise Exchange servers.
For the Hybrid method, you also need Azure AD Connect, to allow your local Active Directory to sync user objects (and passwords) to Office 365.
