When you try to set probes for IMAP and POP3 by running the Invoke-MonitoringProbe cmdlets in a Microsoft Exchange Server 2013 environment, the commands don't run successfully. Additionally, you receive the following exception:
Exception : System.InvalidOperationException: Unable to initialise TCP Network connection ---> System.Net.Sockets.SocketException: The requested address is not valid in its context 127.0.0.1:0
This issue occurs because the Endpoint property is not handled correctly for the ProbeDefinition type.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
