Microsoft runs a little-known program called Home Use Program for Commercial Volume Licensing customers who have active Software Assurance coverage for their Office applications.
You only need your professional email and the program of your organization. Some require employees to use the code to validate their HUP authorization (which is usually administered by a third party).
Employees who participate in the work of this program can purchase these Office applications to use on their own personal device for the duration of their employment.
Interestingly, Microsoft decided not to work with Office 365, which could be useful to promote OneDrive and Office on mobile devices.
Office2016 Professional Plus CD Key Global includes Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher and Skype for Business. Note that the Mac version does not include Access, the Microsoft database management system.
