A vault store and a vault store partition must exist before you enable public folders for archiving. If you want to use Enterprise Vault's optimized single instance storage, ensure that vault store groups, vault stores, and vault store partitions are correctly configured for your requirements.

See the Chapter, Setting up storage, in the Installing and Configuring manual.

If you auto-enable the target public folders for archiving, Enterprise Vault automatically creates archives for the public folders in the vault store selected for the public folder archiving target.
