Office 365 is a subscription service that includes the Office apps you're familiar with, including Word and Excel, which you can install on a combination of up to 15 devices—PC, Mac, tablet, or phone. A subscription also includes perks like oodles of cloud storage and monthly feature updates. Try it free for a month.
If you've already got an Office 365 subscription, you'll need your Microsoft account to log in and install the Office apps or to change your billing or other aspects of your subscription.
