The Home Use Program is a Software Assurance benefit available to Microsoft volume licensing customers with active Software Assurance coverage on their Office applications. Employees who use the covered licenses at work are eligible to purchase these Office applications for use on a personal device during the term of their employment.
Eligible employees are allowed to purchase a single license of either Office Professional Plus 2016 or Office Home and Business 2016 for Mac. Additionally, if part of their organization's Software Assurance benefits, employees may purchase any one of the other products available.
If you are not sure if your organization is eligible, contact your Software Assurance benefits administrator.
