Hello
This type of license is a volume license, not meant for home users, and home users actually don't receive support for this, because Microsoft doesn't sell this type of license anywhere to its retail consumers. It is meant to be distributed via organizational accounts via contracts to their own internal users. If anyone resells those, it is considered a violation of licensing terms.
Did you buy it from a third-party seller? Or did you get the license from your employer/school? Or did you buy this from some discount program via work?
