@ian hickman, Thanks for posting in Q&A. For the message, it seems we don't have all the licenses for Microsoft Managed Desktop. In General, Microsoft Managed Desktop is a cloud-based service that brings together Microsoft 365 Enterprise (including Windows 10 Enterprise and Office 365 Enterprise). Here is a link with more details:

In fact, Microsoft Intune is a cloud service which manages user access and simplifies app and device management across your many devices, including mobile devices, desktop computers, and virtual endpoints.

To manage the devices, we need to enroll the device into Intune. You can choose one suitable method to do the enrollment.

I notice it seems we have the devices in on-premise domain, for these devices, GPO enrollment is recommended.
As a note, before we enroll the device, please ensure the MDM Authority is set to Intune,

All that my tenant is failing on for MDM is licencing. There are user accounts in 365 that are just for things such as booking rooms, so they don't need a 365 licence, but these show as users in InTune, and I believe this is maybe why MDM enrolment is failing on "Licenses"
