Hi Chris Robertson,
You have hit the Entra ID device limit. By default, Entra ID restricts a single user from registering or joining more than 50 devices. However, you need to stop using your own admin account to set up user computers. This is a major bad practice in enterprise environments. When you register a device with your email, Intune makes you the "Primary User" of that device. This will break BitLocker recovery key mapping, Conditional Access policies, and application targeting for the actual user.
Here is how to unblock yourself and fix the process:
1. To immediately raise the limit:
Go to the Entra admin center > Identity > Devices > Device settings. Look for Maximum number of devices per user and increase the value (or set it to Unlimited).
2. The Enterprise Way (How you should be doing it):
Windows Autopilot: Set up Autopilot so users can unbox the machine, type their own email and password, and the device automatically provisions itself with your company policies.
Device Enrollment Manager (DEM): If you absolutely must pre-provision devices for users manually, do not use your personal IT account. Create a dedicated service account and assign it the Device Enrollment Manager role in Intune. A DEM account bypasses standard limits and can enroll up to 1,000 devices.
Fix the limit for now, but definitely look into Autopilot or DEM accounts. If this answers your question, please click "Accept Answer".
