Understand the Box Policy For Browser And OS Support

Box supports the most recent major releases of the following web browsers and desktop/mobile operating systems (OS). If you are experiencing interface issues, try updating your browser or OS to the latest version.


Web browsers:

Note: The end of support for any browser includes the browser in compatibility mode or any other version of compatibility mode that represents the browser.


  • Internet Explorer (IE) - IE 11
    • Older versions of IE are NOT supported including using compatibility modes in IE 11. 
  • Microsoft Edge
    • Box Tools (Box Edit and Device Trust) is not currently supported on Microsoft Edge.
  • Safari - The two latest, released versions on macOS (as specified in the OS section below).
  • Firefox - The two latest, released versions.
    • Firefox versions more than two major versions old, including ESR (Extended Support Release) versions, are not supported
  • Chrome - The two latest, released versions.
    • Box Tools v3 is not supported in Chrome v66+. Please update to Box Tools v4 to continue using Box Tools (Box Edit and Device Trust) in Chrome v66+.  


Note: Certain applications will not function in browser modes that do not support cookies (e.g. incognito mode in Google Chrome), or browsers configured to prevent the creation of cookies.


Operating Systems (OS):

  • Windows - 7 (32-bit and 64-bit), 8 and 8.1 (64-bit), and 10 (32-bit and 64-bit)
    • Note: Box Sync does not support NTFS data deduplication, even if it is enabled in Windows.
    • Note: Box Drive is not supported in either  Windows 8 or Windows 8.1.
    • Support for Windows XP and Vista ended on October 31, 2014.
  • Android -  All versions of Android released within the last three years.
  • OS X - The two latest released versions.
  • iOS - The two latest released versions.
  • Chrome - Box supports Chrome OS so you can natively access your Box files on your Chromebook. Visit the Chrome Web Store to download the application.
      • Box for Chrome OS is currently a publicly available beta release. 



  • Each time a new version is released for general availability, Box begins supporting the update and stops supporting the third-oldest major version.
  • Box provides this Standard End of Life (EOL) policy for browsers and OS for transparency.
  • Box reserves the right to make exceptions from this policy (Examples: if conflicts arise or for security reasons).
  • We recommend keeping all Box applications (Box Sync, Box Drive, Box Tools, etc.) on the most recent available version at all times. If you run into issues with an older version, there may be fixes in the new version that could solve the problem. Our User Services team will recommend this as a first step during the support process if you have not updated.
  • Box will end support for 3rd party dependencies on the same day that the vendor ends support for the given software. Box will make reasonable efforts to provide at least 3 months lead time to upgrade to the supported version of 3rd party libraries/software. However, there may be exceptions to this policy where the EOL timeline might be accelerated (Example: security vulnerabilities in the 3rd party software).


Browser-Specific Upload Limits


IE applies file-size upload and download limits that supersede Box account-level upload limits.

  • Users accessing Box through IE version 11 can only upload files under 4GB in size.

For more information on IE limits, refer to Microsoft's official documentation.
