Setting IGNORENODEFAULT registry entry for custom filtering

If the appropriate registry keys are configured to enable custom filtering and properties for archiving tasks, then certain configuration entities are required to define the default actions of the archiving tasks. For example, if specific targets are to be archived using particular filter rules, then a named XML ruleset file must exist for each of the archiving targets for custom filtering, and a Default Filter Rules.xml file must also exist to provide filtering rules for the other archiving targets serviced by the archiving tasks. If this file does not exist, then the archiving tasks will stop and an error reported in the event log.

Alternatively, if the Default Filter Rules.xml file does not exist, but you configure the IGNORENODEFAULT registry entry, the archiving tasks ignore the fact that the file is missing and use the default archiving task policy settings when archiving all targets that do not have a named ruleset file.

The IGNORENODEFAULT registry entry also enables you to restrict custom filtering to target archiving targets with named ruleset files only. (If the Default Filter Rules.xml file exists, it is used as the default by all archiving tasks enabled for custom filtering.)

Similarly, to apply custom property indexing to specific target archiving locations, you would typically require the following configuration entities:

A Custom Properties.xml file with entries defining the custom properties to index and an associated content category.
A separate, named ruleset file for each of the archiving targets requiring custom property indexing.
In Custom Properties.xml, a default content category to use for all messages archived from other locations that are not covered by the named ruleset files.

However, if you want to restrict custom filtering and custom property indexing to the named targets, it is more efficient to omit setting the default content category in Custom Properties.xml and set the IGNORENODEFAULT registry entry. In this way, custom property indexing is applied only to locations explicitly defined by named ruleset files.

To set the IGNORENODEFAULT registry entry for custom filtering

Log in as the Enterprise Vault Service account on the computer running the archiving tasks enabled for custom properties and filters.
Start Regedit.

Navigate to the following location:

HKEY_LOCAL_MACHINE
\Software
 \Wow6432Node
  \KVS
   \Enterprise Vault
    \External Filtering
     \Journaling|Mailbox|PublicFolder

Right-click the required archiving key (Journaling, Mailbox or PublicFolder) and select New,Key.
Name the new key EnterpriseVault.CustomFilter.
Right-click EnterpriseVault.CustomFilter and create a new DWORD called IGNORENODEFAULT.
Set the value to 1 to ignore missing default files or settings.
This key will apply to all tasks for the selected type of archiving.
Close Regedit.
Restart the associated archiving tasks.
In a distributed environment, where you have archiving tasks running on more than one computer, you need to perform these steps on each computer running archiving tasks that have been enabled for custom filtering and properties.
