Frequently asked questions

Office 2019 is sold as a one-time purchase, which means you pay a single, up-front cost to get Office apps for one computer. One-time purchases are available for both PCs and Macs. However, there are no upgrade options, which means if you plan to upgrade to the next major release, you'll have to buy it at full price.


Microsoft 365 is a subscription that includes the most collaborative, up-to-date features in one seamless, integrated experience. Microsoft 365 includes the robust Office desktop apps that you’re familiar with, like Word, PowerPoint, and Excel. You also get additional online storage and cloud-connected features that let you collaborate on files in real time. With a subscription, you'll always have the latest features, fixes, and security updates along with ongoing tech support at no extra cost. You can pay for your subscription on a monthly or yearly basis, and the Microsoft 365 Family plan lets you share your subscription with up to five members of your household, for a total of six users, and use your apps on multiple PCs, Macs, tablets, and phones.

This means that your Office 365 subscription will automatically be renamed to Microsoft 365. Get everything you love about Office 365, plus additional benefits as they are released, all at the same price. No action is needed from your end. Changes began April 21, 2020.

Microsoft 365 is compatible with PC, Mac, Android, and iOS.4 See system requirements for compatible versions of your devices and for other feature requirements.

No. Microsoft 365 apps are tailored for each platform and each operating system. The apps available for Mac users and the specific features included may be different from those available for PC users. With Microsoft 365, you can be flexible. You’re not limited to exclusively Mac or exclusively PC, so you can transition across devices.

Yes. Documents that you have created belong fully to you. Store them online on OneDrive or locally on your PC or Mac.

Internet access is required to install and activate all the latest releases of apps and services included in all Microsoft 365 subscription plans. Note that if you’re an existing subscriber, you don’t need to reinstall or purchase another subscription.

For Microsoft 365 plans, Internet access is also needed to manage your subscription account, for example to install Office apps 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 Microsoft 365 up to date and to get automatic upgrades. If you don’t connect to the internet at least every 31 days, your apps will go into reduced functionality mode, which means you can view or print your documents but can’t edit the documents or create new ones. To reactivate your apps, simply reconnect to the internet.


You don’t need to be connected to the internet to use the Office apps, such as Word, Excel, and PowerPoint, because the apps are fully installed on your computer.

Your Microsoft account is the combination of an email address and password that you use to sign in to services like OneDrive, Xbox LIVE, and Outlook.com. If you use any of these services, you already have a Microsoft account you can use, or you can create a new account. Learn more about a Microsoft account.


When you sign up for a trial or purchase a Microsoft 365 subscription, you’ll be prompted to sign in with a Microsoft account. You must be signed in with this account to install and manage your Microsoft 365 subscription, or to use some subscription benefits, including OneDrive storage.

You can share Microsoft 365 Family with five other people in your household, for a total of six users. Microsoft 365 Personal can be used by only one person.

If you have an active Microsoft 365 Family subscription, you can share it with up to five members of your household for a total of six users. Each household member you share your subscription with can install Microsoft 365 on all their devices and sign in to five devices at the same time.

To add someone to your subscription, visit the Microsoft account page and follow the on-screen instructions to add a user. Each person you add will receive an email with the steps they need to follow. Once they have accepted and completed the steps, their information, including the installed apps they’re using, will appear on their My Account page. Go to the Microsoft account page to stop sharing your subscription with someone or remove a device they’re using.
