Details

Explanation

This Information event indicates that the Microsoft Exchange Transport service configuration has been updated.

Microsoft Exchange Server 2010 uses an ESE database to store queued messages and configuration information, such as IP allow lists, IP block lists, and sender repudiation information. When changes are made to the transport configuration, the Active Directory directory service notifies the transport server to update its configuration cache. When the transport server receives this type of notification, it reloads the configuration from Active Directory into the cache, and then uses the new information for subsequent message transfer operations.

User Action

No user action is required. However, for more information, you may want to do one or more of the following:

• Review the Application log and System log on your Exchange 2010 servers for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.

• Review the Operations Console in Operations Manager for detailed information about the cause of this issue. For more information, see the "Introduction" section in this article.

• Examine the EdgeTransport.exe.config file to determine whether any Transport settings have been changed. For more information, see Understanding the EdgeTransport.exe.Config File.

• Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and other methods. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
