- You are using an instance of Microsoft Exchange Server that has transport rules configured.
- One or more of the transport rules contains one or more of these conditions:
- When you sending email messages to a large recipient list, you notice a long delay in the delivery of the message to some users.
- You may see the following event recorded in the Application log on the Hub Transport servers:
