How to offboarding endpoint from Purview

Hi CovUser06​,

If you want to remove devices from Purview while keeping them protected by Microsoft Defender for Endpoint, you should download the Windows off‑boarding package from Purview portal > Settings > Device onboarding > Offboarding and run the included script on each device with administrator rights to stop them from reporting to Purview. After running the script, wait for the portal to sync (up to 24 hours) and check that the devices have disappeared from the “Onboarded devices” list. If you have many devices, you can deploy the script in bulk using Intune, SCCM, or Group Policy to offboard multiple endpoints at once. This process removes the devices from Purview DLP tracking while leaving Microsoft Defender fully active.
