         Add-Type -Path ($modulePath + "\Microsoft.SharePoint.Client.dll")
         Add-Type -Path ($modulePath + "\Microsoft.SharePoint.Client.Runtime.dll")
         Add-Type -Path ($modulePath + "\Microsoft.Online.SharePoint.Client.Tenant.dll")
 Write-Output -msg "End : Module loading Process"
 $pwd ="********"
 $Credentials = New-Object Microsoft.SharePoint. Client.SharePointOnlineCredentials($UserName, (ConvertTo-SecureString $pwd -AsPlainText -Force))
