Hello Eben Sutton,
Thank you for your reply.
I apologize for any confusion. Microsoft does not require devices that are joined to a domain to get their Windows license from that domain. It is possible that your device is configured to require a work or school account for certain features or applications.
To resolve this issue, you can try signing in with a different work or school account, or contact your administrator for assistance. Your administrator may be able to adjust the Group Policy settings or disable Windows Information Protection (WIP) if it is enabled.
If the issue persists, you can try resetting your device's activation status by running the following command in an elevated Command Prompt:
slmgr.vbs /rearm
This will reset the activation status and may resolve the issue. However, please note that this should only be used as a last resort and may require reactivation of your Windows license.
Best Regards,
Haijian Shan
