Microsoft 365 ProPlus


Microsoft's Microsoft 365 ProPlus allows individuals with an Microsoft 365 account to install Microsoft Office on up to 5 Windows or Mac computers, 5 tablets, and 5 smartphones.The Microsoft Office applications that are available via ProPlus include Outlook, Excel, Word, PowerPoint, and OneNote.

System requirements

  • To install Office 2016, you need Mac OS X 10.10 or later or Windows 7 Service Pack 1 or later.
  • To use Microsoft 365 ProPlus, you must have an Microsoft 365 account and have been assigned a license. All current Stanford staff, faculty, and graduate students already have an Microsoft 365 account and are licensed. Once your license or account is removed, your installations of Microsoft 365 ProPlus will go into a reduced functionality mode. In this mode, current documents will still be available, but new documents cannot be created.


  • You must connect to the Internet at least once every 30 days to use the Office apps you have downloaded from ProPlus. This is so that the status of your Microsoft 365 subscriptions can be checked. If you don’t connect within 30 days, Microsoft 365 ProPlus goes into reduced functionality mode. After you connect to the Internet and your subscription status is verified, all the features of Microsoft 365 ProPlus are available again. If you know that you will be unable to connect to the Internet at least once every 30 days (for example, if you're traveling to a remote location), please submit a Help ticket to request a different method of obtaining Microsoft Office.

  • To install individual Microsoft Office applications on a mobile device, you can go to the App Store for iOS or the Play Store for Android and search for Microsoft Office.

  • ProPlus is intended for individual use, since it's tied to the Microsoft 365 license of the user. Do not use ProPlus to download software for groups or labs. IT professionals setting up Microsoft 365 for labs or groups should go to the Microsoft Products for Stanford IT Professionals page.

  • Microsoft 365 ProPlus is not the same as Office Online. Office Online lets users open Word, Excel, PowerPoint, or OneNote documents in a web browser.
