Vault Cache and Virtual Vault status

You can check the status and details of Vault Cache synchronization in the Vault Cache Properties dialog box in Outlook on the user's computer.

A Virtual Vault always includes the following search folders:

Could Not Archive. This folder lists items that Vault Cache synchronization could not archive, after the number of attempts configured in the advanced setting Max attempts to archive an item.
To Archive. This folder lists items that the user has moved or copied into Virtual Vault and that are awaiting archiving. The folder does not include items that Vault Cache synchronization could not archive.
