I realised my mistake and was able to dot source successfully. Now when I try to query client data, I get error below New-GraphAPIAuthHeader command isn't available At C:\Users\isaaco\Documents\Get-MDMClientData.ps1:67 char:13 throw "New-GraphAPIAuthHeader command isn't available" ~~~~~~~~~~~~~~ CategoryInfo : OperationStopped: (New-GraphAPIAut...isn't available:String) [], RuntimeException FullyQualifiedErrorId : New-GraphAPIAuthHeader command isn't available Ondrej Sebela

Thank you for the swift reply. I did replace the tenant name and server name. Do I have to name them with the $ in front of the name or not? Ondrej Sebela
