The index of items stored in a user's archive may become out of date if, for example, there is a power failure or an out-of-date system backup is restored.

If there is a problem with the index, Enterprise Vault rebuilds it automatically the next time that an item is archived in that archive. This means that there may be a short period when the index contains out-of-date information about the items that are in the archive. Users searching an archive using the Enterprise Vault Web Access application may not be able to find items until the index is updated.

If you believe that this is the problem, the user can archive an item to force Enterprise Vault to rebuild the index.
