Hi @jarweb , unfortunately, if a device is not joined to Azure AD, it will not appear in the Azure AD sign-in logs. However, there are other ways to track device usage in your organization.
One option is to use Microsoft Endpoint Manager (formerly known as Intune) to manage your devices. With Endpoint Manager, you can enroll devices and track their usage, even if they are not joined to Azure AD. You can also use Endpoint Manager to enforce policies and configurations on devices, and to remotely wipe a device if it is lost or stolen.
Another option is to use a third-party device management solution that integrates with Azure AD. There are many such solutions available, and they can provide additional features and functionality beyond what is available in Endpoint Manager.
Finally, you can also use other logs and tools to track device usage. For example, you can use the Windows Event Viewer to view logs of user logins and logouts on a device. You can also use network monitoring tools to track network traffic and identify which devices are connected to your network.
Please let me know if you have any questions and I can help you further.
