Once your Database Availability Group has been created and configured, the next step is to set up database replication by adding new mailbox database copies of existing databases. In this recipe, we'll take a look at how to add mailbox database copies using the Exchange Management Shell.
Adding mailbox copies to a Database Availability Group
How to do it...

Add-MailboxDatabaseCopy DB01 ' -MailboxServer MBX2 ' -ActivationPreference 2
When running this command, a copy of the DB01 database is created on the MBX2 server.
