If you see these licenses then the IT department has been working slower than their student and teacher needs. These licenses are self service licenses that any eligible student or teacher can sign up for at: http://office 365.com (use .no for Norwegian)

These licenses are not avaliable as a SKU and can not be placed by the distributor or reseller. They are “unlimited” in quantity.

Be aware that this might disrupt automatic license assignment via powershell and can disrupt the teacher/student.

Do not use this SKU unless you really have to. This is a last resort for the users when they are not provided the free services they have the rights to use.
