1) The registry entry "MoveOnFilterFailure" lists a folder called
"Enterprise Vault Journaling Service". Where is this folder? Is this an
exchange mailbox folder?

Is it the folder of the journaled mailbox?

2) Also. Does any one know if this is effected by

KVS_VAULT_SITE > Policies > Exchange > Mailbox > Properties > Archiving
Rules > Advanced

Set Failed Message 'Do Not Archive'



Controls whether the Journaling Service moves messages when an unhandled
error occurs in the external filter.

When MoveOnFilterFailure is in effect, the Journaling Service moves messages
that the external filter cannot handle to the Failed External Filter folder,
which is under the Enterprise Vault Journaling Service folder.

See the Enterprise Vault API documentation for details of how to set up an
external filter.
