CRM for outlook client configuration fails with error - "There is a problem communicating with CRM server", when latest versions of MOSA client is installed which are below:

Microsoft Online Services Sign-In Assistant for IT Professionals BETA

CRM for outlook configuration only works if Microsoft Online Services Sign-In Assistant for IT Professionals RTW (2.1) version of MOSA is installed.

However if we install the Microsoft Online Services Sign-In Assistant for IT Professionals RTW not Beta then the Powershell doesn't work.
