@SteveCo, Thanks for posting in Q&A. If a device is offline at the time a remediation script is scheduled to run, the script will not run on that device until it is online and able to communicate with Intune and Windows Push Notification Service (WNS) during the remote action. The device might not receive the Run remediation device action if it is not online or able to successfully communicate with Intune or Windows Push Notification Service (WNS) when the device action is sent.
Hope the above information can help.
