Microsoft Intune provides device actions such as Wipe/Retire for unused or missing devices. You can wipe/retire the whole device with a remote command from the Intune portal. You must take this action before deleting the user from Azure, as if the user is deleted then you cannot wipe the device.
Wipe action restores the device to its factory default settings. You have the option to keep the data or completely remove it.
Retire action does not remove the user's personal data on the device but it removes all managed app data, configuration, settings that were assigned by Intune. One common example is the Outlook app and its data.
Here you can find how to export the list of devices that are recently wiped from Intune. Azure keeps the logs data only for 30 days.
