- You create a database availability group (DAG) that contains three or more member servers in a Microsoft Exchange Server 2010 environment.
- A router or switch issue occurs, and the issue causes intermittent connectivity between the member mailbox servers in the DAG.
Note The expected behavior is for as few mailbox servers as possible to be removed from the failover cluster for the DAG. This is so that the remaining mailbox servers can still communicate with one another. Therefore, the DAG can continue to run if the cluster still has quorum.
