Explanation

This event indicates that fewer than 10 percent of the Hub Transport servers have been available over a 30-minute period. This scenario indicates that a critical issue may be affecting the availability of Hub Transport servers in the Exchange organization.

This alert may be triggered when one of the following conditions is true:

  • The affected Hub Transport servers are temporarily unavailable

  • The affected Hub Transport servers are offline

Additional troubleshooting may be required to determine whether this issue occurs because of a transient issue or whether the servers are actually offline.

User Action

To resolve this error, 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 Operations Manager for detailed information about the cause of this problem. For more information, see the "Introduction" section in this article.

  • Log on to the server, and then start Windows Reliability and Performance Monitor. Add all performance counters for the MSExchangeMailSubmission object. Then, note the values of the Hub Servers and Hub Servers In Retry entries.

  • 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 others. 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 Technical Support, be sure to review your organization's guidelines first.
