Exchange 2019: configuration of a DAG

In this tutorial, we will see how to configure a DAG with Exchange 2019.

A DAG (Database Availability Group) is the fact of putting one or more databases in high availability under Exchange in order to ensure continuity of service.

The procedure is similar to Exchange 2016 and already available on the site, I will not go into as much detail.


  • Have 2 Exchange 2019 servers with the same level of update (Windows and Exchange).
  • Have a server to store the server quorum when using an odd number of Exchange servers.
  • Exchange servers must have the same partitions
  • Ideally, Exchange servers should have two network cards, one of which is dedicated to replicating databases.
