If you purchased a recurring billing subscription, your subscription starts when you complete your purchase and will continue until cancelled. Recurring billing subscriptions may be purchased from Office365.com, MicrosoftStore.com, iTunes®, and some other retailers. If you purchased a pre-paid subscription, your subscription starts when you activate your subscription and land on your My Account page. Pre-paid subscriptions may be purchased from a retailer or reseller, or a Microsoft support agent.
Visit www.office.com/information for information about the extra features you get on mobile apps when you have Office 365 Home or Office 365 Personal. To unlock the features, sign in to the mobile app using the same Microsoft Account that you used when you bought Office 365.
Internet access is required to install and activate all the latest releases of Office suites and all Office 365 subscription plans. For Office 365 plans, Internet access is also needed to manage your subscription account, for example to install Office on other PCs or to change billing options. Internet access is also required to access documents stored on OneDrive, unless you install the OneDrive desktop app. You should also connect to the Internet regularly to keep your version of Office up to date and benefit from automatic upgrades. If you do not connect to the Internet at least every 39 days, your applications will go into reduced functionality mode, which means that you can view or print your documents, but cannot edit the documents or create new ones. To reactivate your Office applications, reconnect to the Internet. You do not need to be connected to the Internet to use the Office applications, such as Word, Excel, and PowerPoint, because the applications are fully installed on your computer.
If you have an active Office 365 Home subscription, you can share it with your family – for up to 6 people. Each household member you share your subscription with can use any of your available installs on their PCs, Macs, iPads, Android tablets, Windows tablets, iPhones®, or Android phones, get an additional 1 TB of OneDrive storage, and manage their own installs from www.office.com/myaccount.
