Some day ago, I installed a new Exchange 2013 CU11 for some test ins my lab. Nothing fancy, just a single server deployment on a Windows Server 2012 R2 VM. I deployed this Windows Server from a template, which was updated with the latest Windows Patches and WMF some days ago. The Exchange setup went smooth. I updated the SSL certificates and the internal and external URLs for the virtual directories. Then I started the Exchange Management Shell (EMS), to update the Autodiscover URL in the service connection point (SCP) of the Active Directory.

Well… that doesn’t look successful. I quickly switched to a PowerShell windows and imported the Exchange snap-in manually.

Looks better, isn’t it?
I compared my lab setup to a running Exchange 2013 single server deployment and I stumbled over the PowerShell version. In addition, I found the Windows Management Framework 5 Production Preview (KB3066437) on my freshly deployed Windows Server 2012 R2 VM.

After checking the Exchange Server Supportability Matrix, it was clear what had happened: WMF 5 is not supported (Source). Not supported with Exchange 2013, and also not supported with Exchange 2016.
After I had removed KB3066437 from my Exchange server, the EMS loaded successfully.

You can then manipulate this output and organize it in interesting wa ys. For example, to get a quick view in tabular format, use Format-Table: Get-Mailbox | Format-Table Name,Database,RulesQuota VERBOSE: Connecting to exchange1.lab.local.

You should ALWAYS check if installed applications are supported with newer version of PowerShell/ WMF! Currentyl, no Exchange version is supported with PowerShell 5/ WMF 5.

Thank you !!!
