Quick Answer
The answer is that the app’s installation behavior is set to 'System'. This is the most likely cause when a LOB app does not appear in the Company Portal, because Intune installs system-context apps in the device context, running as SYSTEM, while the Company Portal only displays apps installed in the user context. Even though the app is correctly assigned to the right group, the portal filters out system-context installations entirely, making the app invisible to users. On the Microsoft 365 Endpoint Administrator MD-102 exam, this scenario tests your understanding of the critical distinction between user and device installation contexts—a common trap where candidates overlook that assignment alone doesn’t guarantee visibility. Remember the memory tip: “System hides from the user’s eyes”—if you want an LOB app to show in Company Portal, always set installation behavior to ‘User’.
This MD-102 practice question tests your understanding of manage and maintain devices. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You deploy a new line-of-business app to Windows 10 devices via Intune. Users report that the app does not appear in the Company Portal. You verify that the app is assigned to the correct group. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
The app's installation behavior is set to 'System'.
Correct. System-installed apps may not appear in Company Portal.
The app is not supported on Windows 10.
Why wrong: Incorrect. LOB apps are supported.
Users need to add the app manually.
Why wrong: Incorrect. Company Portal should show available apps.
The app is assigned to the wrong group.
Why wrong: Incorrect. The scenario states the group is correct.

Correct answer & explanation
The app's installation behavior is set to 'System'.
When a line-of-business (LOB) app is deployed with installation behavior set to 'System', it installs in the device context and runs as SYSTEM. The Company Portal only displays apps installed in the user context. Even though the app is assigned to the correct group, it will not appear in the Company Portal because the portal filters out system-context apps. To make it visible, the installation behavior must be set to 'User'.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates assume any assigned app will appear in Company Portal, overlooking the critical distinction between system-context and user-context installation behavior in Intune.
Trap categories for this question
Command / output trap
Incorrect. Company Portal should show available apps.
Scenario analysis trap
Incorrect. The scenario states the group is correct.
Detailed technical explanation
Under the hood, Intune uses the Windows Enterprise Side-Loading (WESL) framework for LOB app deployment. When installation behavior is 'System', the app is installed under the SYSTEM account and its package family name is registered in the device context, not the user context. The Company Portal queries the user context for installed apps via the Windows.Management.Deployment.PackageManager API, so system-context apps are invisible. In real-world scenarios, this often confuses administrators who see the app installed on the device but not in the portal.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
