Your administrator can make the Vault Cache feature available to you. A Vault Cache is located on your computer, and contains copies of the items that are in your online vault. You need a Vault Cache if you want to do the following:

Your administrator can choose whether your Vault Cache stores complete archived items or partial archived items. You cannot change this option. A partial archived item includes enough information for Virtual Vault to display it in the Outlook item list, but not the item's full content.

If your Vault Cache stores partial archived items, Enterprise Vault retrieves the full content from your online vault when it is required. For example, Enterprise Vault retrieves the full content of an archived item when you open the item from Virtual Vault. The type of Vault Cache (that is, whether it stores complete archived items or partial archived items) affects the accessibility of archived items when you work offline.

Enterprise Vault regularly synchronizes your online vault and your Vault Cache. Your administrator may also let you start the synchronization process yourself.
