You can use the Modern Config Tool to update your "Remote Powershell URL". You do this by editing the EAS Office 365 configuration. Navigate to the "Email Server Configuration" panel. In that panel, you will see a text box labled "Email Server hostname". You can customize the value in this text box. When you do this, the read-only "Remote PowerShell URL" that is displayed will be updated automatically. The "Remote PowerShell URL" is the value that you enter for the "Email Server hostname", with leading "https://" text and trailing "/powershell" text. If you want to run the older config tool, you do that by using Windows Explorer and navigating to the "C:\Program Files (x86)\MaaS360\Cloud Extender" folder, and running the ASConfig.exe executable.
