Using Intune to have Outlook block personal accounts

[Suhayl_Khatib]

I need help using Intune with outlook to only allow work accounts that are tied to the Azure AD. I would like this done for Windows Devices and a separate policy for iOS Devices. I am entirely stuck on what to do. Any help would be appreciated.
