Fixing Device Limit Errors on iOS with Microsoft Entra

Let’s discuss Fixing Device Limit Errors on iOS with Microsoft Entra. When you try to enroll your iPhone or iPad into Intune, you might see a message in the Company Portal app that says This device is not registered. This usually happens because you have reached the Microsoft Entra device limit for your account.

This issue usually happens in every device in Entra and Intune. This Error means the device was not fully registered due to the device cap being reached. Also, the device might not actually register properly, even though the setup appeared to be successful.

This can cause a confusing problem that is your device shows up in the Company Portal app, but it also has an error message that says it isn’t registered. This happens because Microsoft Entra enforces user per device caps to ensure security and compliance.

That means, if the maximum is set to 5 devices, a user cannot register a 6th device until one of the existing registered devices is removed or the administrator increases the limit. To fix this, administrators can remove stale or unused device entries from the user’s registered devices list in Microsoft Entra. Let’s look detailed workarounds.

Let’s look how this issue solved in this post, In the screenshot below, you can see an example of this error. Even though the device has been enrolled, the Company Portal clearly shows the warning This device is not registered.

  • This message indicates that the device has not been fully registered with Microsoft Entra because the user has already reached their maximum allowed number of registered devices.

Collect Logs from the Company Portal app

Users can collect logs from the Company Portal app. On the bottom menu of the app, select More, then choose Send logs > Email Logs. These logs provide detailed information about why the registration failed and can be shared with the IT administrator for troubleshooting.

Workarounds – Remove Old Devices

To fix this, administrators can remove stale or unused device entries from the user’s registered devices list in Microsoft Entra. This frees up space so that the new iOS device can successfully register. Admins should carefully validate which devices are inactive to avoid disrupting access on active ones.

  • So to do this  navigate through the Navigate to Microsoft Entra ID > Users.
  • Search for the user using their UPN.
  • Select Devices.
  • This displays a list of registered devices for the user. Devices that are no longer in use can be removed.

Increase the Device Limit

By default, Microsoft Entra allows a set number of devices per user, often limited to 5. To increase this limit, administrators need to navigate to the Microsoft Entra Admin Center, go to Devices, and then select Device settings.

  • Locate Maximum number of Devices Per User.
  • Adjust the device limit as needed.
  • Here shows there are maximum number of device per user is 100.

ReEnroll Devices If it Needed

To fix this, first remove the device from Microsoft Entra. Then, reset the device’s management profile on the device itself. Finally, re-enroll the device using the Intune Company Portal. Sometimes this will help you to solve the issue.
