When the user is enrolling and they go select their work account to enroll with, an "Apple ID' window pops up with the users work email address (not their Apple ID), the system won't take their Apple password or their work password. It is not happening to everyone, just about five out of thirty people enrolled so far. They can log into the Microsoft exchange on their phone with their work ID and password to access their emails, calendar and contacts. They just can't enroll in to Intune. Has any one come across this problem?
