Explanation:
To allow Configuration Manager to manage mobile devices in the same context as other devices, it requires you to create a Windows Intune subscription and synchronize user accounts from Active Directory to Microsoft Online. To achieve that, you are required to complete the following tasks:
Sign up for a Windows Intune organizational account

Add a public company domain and CNAME DNS entry

Verify users have public domain User Principal Names (UPNs)

If you plan to use single sign-on, deploy and configure Active Directory Federated Services (ADFS)

Deploy and Configure Active Directory Synchronization

Reset users Microsoft Online password - If not using ADFS*

Configure Configuration Manager for mobile device management

Create the Windows Intune Subscription in the Configuration Manager console

Add the Windows Intune Connector Site System role

Verify that Configuration Manager successfully connects to Windows Intune
