We have set up a test company and want to test Intune MDM. Unfortunately, you need to logon with an Apple Id which is defaulted to the test company credentials used in the portal. So, logging in as joe@company.onmicrosoft.com sets the Apple Id as joe@company.onmicrosoft.com. You cannot create an Apple Id with this email as it doesn't recognize it as being a valid email address. Is there some workaround here? Otherwise, it seems like any companies using xxxx.onmicrosoft.com domains will not be able to use Intune MDM.
