A string value containing a semicolon-separated list of DLL file names.
The default value is "googledesktopoffice.dll;mssphtb.dll".
The file googledesktopoffice.dll is the Google Desktop Search Outlook Add-In. The file mssphtb.dll is the Outlook Microsoft Search (MSSearch) Connector, which provides Windows Search email indexing.
If you set this registry value, include the two default DLL file names. These file names are not automatically added to the list.
Controls the behavior of Virtual Vault when an item is opened.
If the request to open the item comes from one of the named DLLs, then the opened item contains only header information. The Enterprise Vault Outlook Add-In does not retrieve the content from Vault Cache or download it from the Enterprise Vault server.
