Hi @Dheeman Das
It is essential that you push Company Portal when using intune. The Company Portal assists with managing your device/apps/compliance. The Company Portal is a great tool and helps with assigning devices to users and pushing apps to your users.
Can you remove a device from the Company Portal?
During removal, Company Portal unenrolls and unregisters the device from Intune. That device loses access to the Company Portal. Work and school data might also be removed.
Can you remove a device from the Microsoft Intune app?
No, there's no way for you to remove a corporate-owned device from the Microsoft Intune app.
