Rename Exchange 2016 Default Database

Just like previous version of Exchange, Exchange 2016 installation also creates a default database with the name “Mailbox Database 123456789” in default installation directory. In my case, the default database is being created at If you installed Exchange to the default path then the mailbox will be stored in “C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\”.
