Company Portal is the app that lets you, as an employee of your company, securely access those resources.
Before you can use this app, make sure your IT admin has set up your work account. Your company must also have a subscription to Microsoft Intune.
On occasion it may be necessary to verify your Company Portal settings on your iPhone when you try to open a Company application e.g. Outlook:
Click "OK" , then locate and open your Company Portal icon.
