You can check if your device can support your version of Office by viewing the full Office system requirements.

No. Office applications are tailored to work best on each platform and device. The Office applications available for Mac users and the version numbers may be different from those available for PC users.

Office 365, Office 2019, Office 2016, Office 2013, Office 2010, Office 2007, Office for Mac 2011, and Office for Mac 2008 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. Learn what happens if you cancel your subscription.

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 31 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, simply reconnect to the Internet.

Your Microsoft account is the combination of an email address and password that you use to sign in to services like Hotmail, OneDrive, Windows Phone, Xbox LIVE, and Outlook.com. If you use any of these services, you already have a Microsoft account that you can use, or you can create a new account. Learn more about a Microsoft account. As part of signing up for a trial or purchasing Office, you will be prompted to sign in with a Microsoft account. You must be signed in with this account to install and manage your Office software, or to use some subscription benefits, including OneDrive storage and Skype minutes.

Users can activate 1 subscription for Office 365 Home and Office 365 Personal and up to 25 licenses for Office Home & Student 2019, Office Home & Business 2019, and Office Professional 2019.

To set up your account and install Office for the first time, visit https://setup.office.com. Learn more about setting up your account. If you have already created your account, visit accounts.microsoft.com. Learn more about installing Office.

A Product Key is a unique 25-character alpha-numeric code used to redeem and activate your Office product. You cannot use a product key for an older Office product (or a different product) to redeem your new copy of Office.

After you associate your Product Key to your Microsoft account, you can sign in to accounts.microsoft.com to install and manage Office. But it's a good idea to keep your Product Key in a secure location as proof of purchase or to help our support agents trace your product.

It's best to use your existing Microsoft account. If you use other Microsoft products or services (e.g. Xbox, OneDrive, Outlook.com, MSN or Bing), you may already have a Microsoft account and won’t need to create a new one. If you forgot your username or password, recover those details by returning to sign in and clicking on Can't access your account?

If you have installed Office on the maximum number of PCs, Macs, or tablets and want to use Office on a different device, you can deactivate a device by visiting accounts.microsoft.com, after which you can install Office on a new device. The copy of Office on the device you deactivated will revert to read-only mode, which means documents can be viewed but not edited. You will not lose any documents that are saved locally on the original device.

To uninstall Office, first visit accounts.microsoft.com and follow the onscreen instructions to deactivate Office. Deactivating Office leaves the Office applications on your PC in read-only mode, which means that you can view documents but can't edit or save them, and you can’t create new documents. To remove Office entirely, go to your PC's Control Panel and uninstall Office. For Mac, iPad, and Android tablets, follow the instructions on that device to uninstall an application.
