A vault store group, vault store, and vault store partition must exist before you enable mailboxes for archiving. After you enable the target mailboxes for archiving, Enterprise Vault automatically creates an archive for each mailbox in the selected vault store.

To control where Enterprise Vault creates new mailbox archives, you can set the default vault store at the following levels:

When you create a Provisioning Group, the default vault store is inherited from the Exchange Server properties. If an override vault store is not specified in the Exchange Server properties, then the vault store that is specified in the Enterprise Vault server properties is used.

See the "Setting up storage" chapter in the Installing and Configuring manual.
