If Using Email Client Agents and the Exchange Server Agent

If you want to quarantine emails without notifying the sender, you must use the Exchange server agent. It is not possible to quarantine emails silently using an Outlook client agent. This has implications if your CA DLP deployment uses both Outlook client agents and the Exchange server agent.

By default the Exchange server agent does not reprocess emails that have already been processed by a CA DLP Outlook client agent. Therefore, an email cannot normally be quarantined by the Exchange server agent if other policy triggers have already been applied by an Outlook client agent.

To overcome this, you must explicitly configure the Exchange server agent to reprocess (and apply quarantine actions) to emails already processed by a client agent. To do this you must edit the registry on the Exchange server. Go to this registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA DLP\CurrentVersion\Exchange

Within this registry key, add the following value:

ReprocessClientEmails
