1 - Only deploy forms when there is no Organizational Forms
Library available (default).
2 - Always deploy forms locally.
3 - Always delete Enterprise Vault forms from the user's
Personal Forms Library.
Description
Specifies whether, when the user starts Outlook, the Enterprise
Vault add-in determines whether the Enterprise Vault forms are
installed or need updating and then adds or replaces them as
necessary.
This enhancement is required to enable Enterprise Vault to store
forms in each user's Personal Forms Library in an Exchange 2007
environment when there is no Organizational Forms Library.
