Windows 10 - Digital License for Enterprise not working for some users

CGacek 

No, no good all-encompassing solution. Management changed and with it what I was focusing on. What I can say is that one of the causes of this for us was users who had added another organisational account to their devices (for instance, a university account for those people taking courses, etc.). If when adding the external account, they kept the "Allow my organisation to manage my device" box ticked as in the below dialog, having two organisations managing the device got in the way of Enterprise licence activation.

In this article it gives the registry entry to take away the ability to accidently give partial management of the device to another organisation, but it doesn't fix any which are already in that state (though removing the associated registry entries for the other organisation does). Nor was it the only apparent cause of this issue as there were a good number who the above was not the case, and I didn't ever get to the bottom of why their licences weren't activating.
