PowerShell & Office 365 Remoting Broken - Fix

Obsolesce

If you are unable to connect to O365 via PowerShell and get an error similar to below, follow these instructions.

Error:
Import-PSSession : Could not load type ‘System.Management.Automation.SecuritySupport’ from assembly
‘System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’.

The fix:

Open up an elevated PowerShell prompt and type:
wusa /uninstall /kb:3176934
Reboot required

wusa

Thanks.

Just to clarify: PowerShell is not required here because wusa(.exe) is a regular executable file, not a cmdlet. Any other way that let you execute a program with elevated rights will do (e.g. cmd.exe, shortcuts, ...)
