  • 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.
  • Microsoft 365, Office 2021, 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 Microsoft 365 subscription plans. For Microsoft 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.

    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.

  • 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 Microsoft 365 Family and Microsoft 365 Personal and up to 25 licences for Office Home & Student 2021, Office Home & Business 2021 and Office Professional 2021.

Product keys, redemption, and activation

  • To set up your account and install Office for the first time, visit https://setup.office.comLearn 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 alphanumeric 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.

    To find your Product Key, look for the 25-character alphanumeric code on the back of the card inside your Office product packaging. Sometimes the Product Key may be printed on your retail receipt. If you purchased Office from a PC manufacturer, your Product Key will be located somewhere in your PC packaging. Sample Product Key format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

    Get information on locating your product key.
  • 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 have forgotten your username or password, recover those details by returning to sign in and clicking on Can’t access your account?
