How to change priority of transport agents in Exchange PowerShell

Exchange organizations may use the Journaling Agent of the Transport Service to archive messages going through Exchange. However, if the Transport Service is integrated with some email content management application (such as an anti-spam), the administrator may prefer to send messages to Journaling only after they have been sifted by the said software in order to avoid unnecessary cluttering of the archive mailbox. In order to let the application process messages before delivering to Journaling, the administrator will have to set appropriate priorities for Transport Agents using Exchange PowerShell. The video shows how to check the priority of agents for Transport Service and modify the hierarchy. CodeTwoExchangeRulesPRO agent is used in this video as an example of an email content management application. Its priority is changed from 4 to 2 in order to move the agent before the Journaling Agent.
