Office 365 Business and ProPlus subscribers can install Office on up to 5 PCs or Macs, 5 tablets, and 5 smartphones. You can count hybrid Windows devices, such as the Microsoft Surface Pro, as either a PC or a tablet.
Internet access is required to install and activate all Office 365 plans and to manage your subscription account. Internet connectivity is also required to access Office 365 cloud productivity services, including email, conferencing, IT management, and other services.
Many Office 365 plans also include the desktop version of Office, for example, Office 365 Business Premium and Office 365 Enterprise E3. One of the benefits of having the desktop version of Office applications is that you can work offline and have the confidence that the next time you connect to the Internet all your work will automatically sync, so you never have to worry about your documents being up to date. Your desktop version of Office is also automatically kept up to date and upgraded when you connect to the Internet, so you always have the latest tools to help you work.
You don't need to install anything in order to use Office 365.
To help you easily connect your desktop version of the latest version of Office, Office 2013, Office 2010, or Office 2007 to Office 365, Microsoft provides Office 365 customers an installable piece of software—called “Office Desktop Setup”—at no charge. Office Desktop Setup provides many benefits, including:
Automatically detecting necessary updates.
Installing updates and components upon approval or silently from a command line.
Automatically configuring Outlook and Microsoft Skype for Business for use with Microsoft Office 365.
Uninstalling itself from the client computer after running.
You can find and install Office Desktop Setup in your Office 365 administration center.
If your plan includes a subscription to Office, you will also be able to install that directly from the Office 365 administration center.
Office 2007, Office for Mac 2008, Office 2010, Office for Mac 2011, Office 365, Office 2013, and Office 2016 applications can open your documents without any additional action. Customers using earlier versions of Office may need to download and install a compatibility pack.
Yes. Documents that you have created belong fully to you. You can choose to store them online on OneDrive or locally on your PC or Mac.
