What are Mobile Application Management policies?
According to Microsoft:
Mobile application management policies in Microsoft Intune let you modify the functionality of apps that you deploy to help bring them into line with your company compliance and security policies. For example, you can restrict cut, copy and paste operations within a managed app, or configure an app to open all web links inside a managed browser.
For example; when you first attempt to deploy a managed application, such as Skype for Business, you may receive the following informational dialog.
"The software you are trying to deploy must be associated with a mobile app management policy and there are currently none defined. Create a policy from the Policy workspace."

Note: This policy is not deployed, it will be associated with a subsequent app deployment. Also, note the available Managed Browser policies.
