Microsoft Office 365

What's the difference between Office 365 and Office 2016?

Office 365 is a subscription service that includes the most recent version of Office, which currently is Office 2016. It comes with the applications you’re familiar with, like Word, PowerPoint, and Excel, plus extra online storage, ongoing tech support at no extra cost, and more.

You can choose to pay for an Office 365 subscription on a monthly or yearly basis, and the Office 365 Home plan lets you share your subscription with up to four members of your household. Different Office 365 plans are available for home and Personel use, as well as for small and midsized businesses, enterprises, schools, and nonprofits.

Office 2016 is also sold as a one-time purchase, which means you pay a single, up-front cost to get Office applications for one computer. One-time purchases are available for both PCs (such as Office Home & Student 2016) and Macs (such as Office Home & Student 2016 for Mac). One-time purchases don’t have an upgrade option, which means if you plan to upgrade to the next major release, you'll have to buy it at full price.

Can I buy just one app, like PowerPoint? What about Project or Visio?

Yes. You can buy standalone versions of Word, Excel, and PowerPoint for Mac or PC.

You can also get a one-time purchase or a subscription version of Visio or Project, available for PCs only.


I have a Mac. What should I buy?

Office 365 subscriptions work on both Macs and PCs. However, if you want a one-time purchase of Office, you’ll need to buy Office Home & Business 2016 for Mac or buy Office Home & Student for Mac. The primary difference between these two products is that Office Home & Business 2016 for Mac includes Outlook and is licensed for business use.


Do I need to be connected to the internet to use Office 365?

You don't need to be online to use Office after it is installed and activated on your devices. However, you will need internet access initially to install and activate Office, to install any updates, and to manage your billing. Internet access is also required to access documents stored on OneDrive, unless you install the OneDrive desktop app. However, after your Office applications (like Word, PowerPoint, and Excel) are installed, you can use them offline.

You should connect to the Internet regularly to keep your version of Office up to date and benefit from automatic upgrades. If you don’t connect to the Internet at least every 39 days, your applications will go into reduced functionality mode, and you might see an unlicensed product error. To reactivate your Office applications, simply reconnect to the Internet and sign in to Office 365.
