Initial synchronization

When a mailbox is enabled for Vault Cache, header synchronization starts when the Vault Cache wizard finishes. Content download may also be performed, if the content strategy requires content download. If the archive contains a large number of items, content download takes much longer than header synchronization.

You can control the maximum age of items in the initial content download using the Vault Cache advanced settings Download item age limit and Lock for download item age limit.

A Virtual Vault is automatically added to a user's profile when the following criteria are met:

The Enterprise Vault archiving task has processed all the archives that the user can access.
The initial header synchronization has completed.
The user has not previously removed the Virtual Vault from the profile.

If a Virtual Vault does not appear automatically in the Navigation Pane, the user can select it on the Virtual Vault tab in Outlook (Tools > Enterprise Vault > Vault Cache Properties > Virtual Vault).
