[Update 2010-01-14: DisclaimIt 4.5 will automatically fix the ordering of the transport agents if changed by Service Pack install or accidental misconfiguration.]


DisclaimIt 4.0, 4.1 and 4.2 stops to process messages after MXS 2007 SP2 is installed. This is caused by the fact that the SP2 installer changes the priority of the registered transport agents: The 'Transport Rule Agent' is now called after the 'DisclaimIt Message Processor Agent' for a message. This means that when the 'DisclaimIt Message Processor Agent' sees the message, the message contains no indication how to process it because this indication is added afterwards by the 'Transport Rule Agent'.

To resolve this problem caused by MXS 2007 SP2, either execute the following commands in the Exchange Management Shell:

$ta = Get-TransportAgent
Set-TransportAgent -id "DisclaimIt Message Processor Agent" -Priority $ta.length
Restart-Service -name MSExchangeTransport

or execute the attached PowerShell script.
