Recently ran into an unknown error while trying to create the Intune connector in ConfigMgr 1602 (and 1606). The error occurred in the “Create Microsoft Intune Subscription Wizard” when trying to Sign in using a Global Admin Azure account.
For those of you who do not understand Danish (yet), the error message is something like “An Unexpected error occurred”.
The GA Azure account is a “service account” and not used to enroll mobile devices. For that reason the account wasn’t assigned an Enterprise Mobility Suite (EMS) license.
The solution: Assign an EMS license in Azure Active Directory to the Global Admin Azure account and sign-in again. You do not have to add the account to your custom Intune collection.
