The Microsoft Exchange Server 2010 Management Pack for System Center Operations Manager runs Exchange Management Shell cmdlets to monitor your Exchange organization. Running cmdlets triggers one or more Operations Manager alerts if a problem is detected.

To learn more about this alert, in Operations Manager, do one or more of the following:


Product Name


Product Version

14.0 (Exchange 2010)

Event ID


Event Source

MSExchange Monitoring POPConnectivity

Server Role

Ex14. Client Access

Rule Path

Microsoft Exchange Server/Exchange 2010/Client Access/POP3/POP Connectivity

Rule Name

POP3 connectivity transaction failures.


The cmdlet that triggered this alert is the Test-PopConnectivity cmdlet. The Test-PopConnectivity cmdlet can be used to verify that the Microsoft Exchange POP3 service is running as expected.

One or more failures occurred when running the cmdlet to evaluate POP3 connectivity. This may be a temporary problem that is keeping this cmdlet from running correctly. For example, this alert may be generated if a backup process on the Mailbox server is preventing the cmdlet from running.

User Action

To resolve this error, do one or more of the following:

  • Wait for the Test-PopConnectivity cmdlet to run again.

  • Check connectivity between the Client Access Server and Active Directory.

  • Make sure that the Mailbox server is running.

  • 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.

  • To review detailed information about the cause of this alert, use the Operations Console in Operations Manager. For more information, see the introduction to this topic.

If you are not already doing so, consider running the Exchange tools created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
