What features does the Microsoft Home Use Program (HUP) offer?

The Microsoft Home Use Program (HUP) is a Software Assurance (SA) benefit, providing access to discounted on-premise licenses or online services (Office 365 Home or Personal) for employees of Microsoft customers. With on-premise licenses, the HUP offer is tied to the use of licenses in the customers business environment. For example, a Visio 2019 Professional user can purchase a discounted and corresponding Visio 2019 Professional HUP license for private use. Important: since July 2019 Office Professional Plus licenses cannot by purchased anymore via HUP. However, the Product Terms do not state that this change leads to an expiration of the licenses.
