I ran a blog post recently that showed you the process of getting a Windows 10 phone enrolled by hybrid Intune into ConfigMgr.
This companion piece shows you how to set up the Company Portal app on your iOS device for the first time.
Go to the App Store on your iOS device and download the Company Portal app.
Open the app and tap Begin to start the enrolment process
Continue through the next few screens until you are prompted to ‘Enrol’.
You’ll be asked to install the Management Profile. Tap ‘Install’
Hit ‘Install’ again.
And again at the Warning screen.
Select ‘Trust’ when prompted.
and hit ‘Done’ when the Management Profile has completed installation.
The device is enrolled and set up ready to be managed in ConfigMgr. Tap ‘Continue’
Select ‘Done’ to compete the task.
The iOS device will appear in the ConfigMgr console shortly after.
