MD-102 Manage and maintain devices Practice Question
You are troubleshooting an iPhone that cannot enroll in Microsoft Intune. The user receives an error stating 'This device is already enrolled in another MDM.' What is the most likely cause?
⚠ Common exam trap
It's easy for candidates to confuse MDM enrollment conflicts with other common issues like outdated OS or licensing, but the specific error message directly points to an existing MDM profile, not generic configuration or access problems.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The device is already enrolled in Apple Business Manager or another MDM.
The error 'This device is already enrolled in another MDM' indicates that the iPhone has an existing MDM profile that conflicts with Intune enrollment. This typically occurs when the device is already enrolled in Apple Business Manager (ABM) or another MDM solution, as iOS enforces a single MDM enrollment per device. Intune cannot overwrite an existing MDM profile without first removing it.
