| Description | Agent '%1' caused an unhandled exception '%2: %3' while handling event '%4' |
| Event Information | According to Microsoft : Cause : This Warning event indicates that the transport agent referenced in the event description has encountered an unhandled exception while handling the SMTP event. Transport agents let you install custom software created by Microsoft, by third-party vendors, or by your organization, on to a Microsoft® Exchange Server 2007 server. This software can then process e-mail messages that pass through the transport pipeline on a Hub Transport server or Edge Transport server. Custom transport agents provide additional functionality to Exchange 2007, such as anti-spam or antivirus programs, or any transport function that your organization may require. Transport agents are typically installed automatically as part of applications that are designed to function together with Exchange 2007. However, there may be instances where organizations want to develop their own transport agents to manage mail that flows through their Exchange 2007 organization. Resolution : If this warning frequently occurs, do one of the following: 1.If the transport agent is created by Microsoft, contact Microsoft Product Support. 2.If the transport agent is not created by Microsoft, contact the third-party vendor who supports the respective transport agent. |
