A:AnswerI had about a month left on my subscription, installed on Windows PCs. I bought a new iMac and Office was $20 off. The new subscription added on to the time I had remaining. And yes, mixed Windows and Mac devices now, no problem.
A:AnswerYou just have to log into the Microsoft account on the other PCs. So you can have 6 users and then it is however many devices you want. I log into mine on a MacBook, desktop, phone, surface and iPad. Then my mom has her own log in under the same account. She is logged into about 5-6 devices herself as well. We can still add 4 more people and they can log into all of their devices too.

A:AnswerI use it for five office machines. If you need five more just buy another card and register it under a employee's name. As long as the e-mails are different, they won't stop you.
