If the Public Folder Targets within the Vault Admin Console (VAC) do not contain auto-enabled targets off the Root target, and the existent Public Folders still contain the Enterprise Vault hidden message, the Public Folder Task will not recreate the auto-enabled targets. Without the auto-enabled targets, the child Public Folders will not be archived.
Original Target : \ (Root), set as Auto-enabler.
- This will enable each Child folder under Root as individual Archives.
If the Child auto-enabled targets are no longer present, and the folders still contain the original hidden messages, the Public Folder Task will not regenerate the auto-enabled targets as it is thought that the folders are already enabled.
When DTracing the PublicFolderTask process, the following may be observed:
(PublicFolderTask) <1584> EV:M CTaskControl::GetTarget - Entry not found in map [\AutoEnabledFolder] Current target count 
(PublicFolderTask) <1584> EV:M CPublicFolderTargetList::GetTarget[ByKey] - Path [\AutoEnabledFolder] Not Found in Map. Note this is a valid condition for New Folders
If the PublicFolderTarget table in the EnterpriseVaultDirectory database no longer contains auto-enabled targets, and the Public Folders still have their associated hidden message (IPM.EnterpriseVault.Filter), the Public Folder Archiving Task will not recreate the auto-enable targets.
Delete original hidden messages from auto-enabled target folders. This can be performed by utilizing the following article to remove the IPM.EnterpriseVault.Filter message from the previously auto-enabled Public Folder.
