function Remove-IBMAutopilotDevice { <# .SYNOPSIS Removes a device from Autopilot based on its Intune Device ID without deleting the device from Intune. .DESCRIPTION The Remove-IBMAutopilotDevice function allows you to remove a device from Autopilot. Devices are identified by their Intune Device ID. This function will not delete the device from Intune itself, only from the Autopilot service. .NOTES Author: Florian Salzmann | @FlorianSLZ | https://scloud.work Version: 1.1 Date: 2024-08-10 Changelog: - 2024-08-07: 1.0 Initial version - 2024-08-10: 1.1 - Added batching / batch requests for large device collections and speed improvements #> param ( [parameter(Mandatory = $false, HelpMessage = "Specify the ID of the individual device to remove from Autopilot.")] [string]$DeviceId, [parameter(Mandatory = $false, HelpMessage = "Specify the name of the group to which the devices belong.")] [string]$GroupName, [parameter(Mandatory = $false, HelpMessage = "Specify the name of the individual device to remove from Autopilot.")] [string]$DeviceName, [parameter(Mandatory = $false, HelpMessage = "Specify the operating system of the devices to remove from Autopilot.
