Microsoft Office and Microsoft 365 give you access to the programs you need to work, play, and stay connected. From the power to create documents and presentations, to the ability to design database apps and stay in touch via email, Office simplifies the way you work online, and off.
What you might not realize, is that Office comes in a variety of versions designed for different needs, uses and computers. But before you buy, let's compare Microsoft Office versions so you can choose the right software for all the things you do.
Microsoft 365 Apps for Business: Designed for use on up to 5 PCs or Macs, as well as 5 tablets – including iPad, Android, or Windows, and 5 phones. In the package, you'll receive access to Word, Excel, OneNote, PowerPoint, Outlook, Publisher and Access. In addition, you'll automatically receive the latest Office updates (including Office 2016), and get 1TB of OneDrive cloud storage, free Microsoft Answer Desk support and 60 minutes of Skype calling per month.
Microsoft 365 Personal: When you compare Office versions, Microsoft 365 Personal gives you all the same great features you'll find in Microsoft 365 Apps for Business, but on just one PC or Mac and one tablet device, instead of up to five of each.
Office 2016 Home & Student: Microsoft Office 2016 features new, modern versions of Word, Excel, PowerPoint, and OneNote that are designed to help maximize your productivity and give you rich authoring features, design controls for pixel-perfect layouts and intuitive tools to help you make the most of your data. Plus, because you'll have access to your docs in the cloud whenever you need them, you can work when, how and where it suits you best. And for those times when collaboration is critical, you can even share documents and get your team on the same page. (Designed for use on one PC.)
Office 2016 Home & Business: With the same great features as Office 2016 Home & Student, as well as Outlook, Office 2016 Home & Business gives you everything you need to get more done -- and stay connected with friends, family and colleagues around the globe.
