Consider the following scenario:
In this scenario, an email message that meets the SCL threshold is not sent to the quarantine mailbox address as expected.
This problem occurs because of the designed behavior that occurs when FPE is installed on Exchange Server Edge. For more information about this behavior, see the blog post that is mentioned in the "References" section.
When the FSE Antispam Filtering option is enabled, the Content Filter agent in Exchange Server 2010 is disabled. Therefore, all Content Filter settings that are configured on TMG are ignored. These settings include the redirection of email messages to the configured quarantine mailbox.
To resolve this problem, install the service pack that is described in the following Microsoft Knowledge Base article:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
After you install Service Pack 2, a new alert in the Content Filtering area of TMG is added to notify the TMG administrator of the problem that occurs when FPE antispam filtering is enabled and the Exchange Content Filter agent is disabled.
