Exchange Online Management module not loading in Active Roles

It is suggested that the version of Active Roles be 7.5.x or newer and that the 'O365 script execution configuration' workflow step is added to an Automation Workflow and not a Change Workflow.

The sample scripts in the 7.5.3 Admin Guide should function as expected.

Active Roles 7.5.3 - Administration Guide (oneidentity.com)

Make sure to select the Azure Tenant within the properties of the 'O365 script execution configuration' workflow step.

Are any errors being generated?

Following code lines I've written in OnPreCreate of an user object

function onPreCreate($Request)
{
try{
WriteLog "Exchange Online Connection Establishing!"
$context.O365ImportModule("Exchange Online")
WriteLog "Exchange Online Connection Established!"
}
catch [Exception]{
WriteLog "Exception caught!"
WriteLog $_
}
}

while importing 'Exchange Online', I got following error 

'Specified Mdoule exchange onlinenot supported'

Thanks
