Recently I have been talking about Exchange Server 2010 and PowerShell and a consistent theme seems to be emerging. A few blog posts on internet also seem to contribute to the misconception that I am going to talk about.

The requirement for Exchange Server 2010 is PowerShell 2.0. When you connect to Exchange Server 2010 using Exchange Management Shell or from a client machine running PowerShell 2.0, it uses Windows Remote Management (WinRM) 2.0.

The requirement and use of WinRM 2.0 causes some confusion it seems.

When you connect to Exchange Server 2010 either using Exchange Management Shell (EMS) or using PowerShell 2.0 from a remote client machine, it uses WinRM features and creates a remote session to the Exchange server (even when EMS is launched from Exchange server it is connecting to).

If you have read about how to enable a computer to receive remote PowerShell connection requests, you may have come across articles like this one on MSDN which shows you that running “winrm quickconfig” will create a listener and allow you to connect remotely to the server in question using Powershell remoting.

Note that the article clearly states WinRM 2.0 will create listener on port 5985. When you connect remotely to Exchange Server 2010, you are connecting to “http://server fqdn/powershell”. You are not connecting to port 5985. You are not connecting to the listener created by WinRM. You are actually connecting to PowerShell virtual directory created by Exchange install and served by IIS.

If the server is built without any WinRM customizations and Exchange Server 2010 is running on it, there are no WinRM listeners configured. You can confirm this by running “winrm enumerate winrm/config/listener”. Even if server administrator has created a listener either manually or via GPO, the listener is still not used for EMS connection or remote PowerShell connection to Exchange Server configuration.

So if anyone tells you to run winrm quickconfig in order to be able to manage your Exchange Server 2010 environment remotely, you can debunk the myth with knowledge you now have!
