Box Ending Support for Internet Explorer 9 and 10

As of September 26, 2016, Box will discontinue support for Internet Explorer 9 and 10 including any version of compatibility mode that represents IE9 or IE10 in alignment with Microsoft's support cycle for these products. Usage of these browsers pose a security risk since these browsers will no longer receive security updates.

As of January 12, 2016, Microsoft stopped supporting IE browsers 9 and 10 for the Windows operating systems that Box supports - Windows 7, Windows 8 (64-bit only) and Windows 10. Microsoft supports Internet Explorer 11 on Windows 7 and Windows 8 and Microsoft Edge on Windows 10.

What Should You Do If You Are Using These Browsers?

All IE9 and IE10 users must upgrade to IE11 or an alternative supported browser in order to continue using Box after the September 26 end-of-support date. Failure to upgrade will result in an inability to access Box's web application with the latest updates.

Why did Box decide to EOL Internet Explorer 9 and 10?

  • Microsoft has discontinued support for IE9 and IE10 on January 12, 2016 and will no longer release security updates making these browsers vulnerable to attacks. (e.g. IE 9 doesn't support policies such as CSP)
  • Maintaining backwards compatibility with much older technologies hinders Box’s ability to innovate and use the best technologies available today.
  • Box is unable to provide a quality preview experience to their users because IE9 doesn't support new libraries such as PDF.js.
  • Box is unable to provide quick and responsive UI to IE 9 users for lack of support with CSS transitions and animations, form validation, and more.
