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:

• Internet Explorer (IE) - IE 11
• Older versions of IE are NOT supported including using compatibility modes in IE 11.
• Folder uploads are no longer officially supported, and functionality will be removed December 27, 2019.
• Microsoft 365 apps and services will no longer support Internet Explorer 11 beginning on August 17, 2021. For more information, please see this announcement from Microsoft.

• Microsoft Edge
  
  • The latest two versions of the new Microsoft Edge (Chromium-based)
  • Box Tools (Box Edit and Device Trust) and Box Notes are not supported on the legacy version of Microsoft Edge (non-Chromium).

• 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+.

Operating systems (OS):

• Windows & Windows Server - The two latest released versions (32-bit and 64-bit)

  • Box Sync does not support NTFS data deduplication, even if it is enabled in Windows.
  • Box Drive is not supported in either Windows 8 or Windows 8.1. However, Box will continue to support only the latest Windows 7 (Professional & Enterprise) Extended Support Updates.

• macOS - The two latest major versions. For Mac devices with M1 chips:
  • Public Beta access for Box Drive is available for users on M1 devices.  Access the Box Drive M1 Public Beta installer and installation instructions here. 
  • Box Tools is fully supported on M1 devices
  • Box Sync is not supported on M1 devices
• Android - All versions of Android released within the last three years.
• iOS - The two latest released versions.

Notes:

• Each time a new version is released for general availability, Box begins supporting the update and continues supporting the most recent prior version. For all versions before that, Box ends support.
• 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 Product Support 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 4 GB in size.
• A file whose name contains more than 50 characters may not be downloadable via IE11, due to IE11's limitation on URL length.

For more information on IE's file loading limits, see Microsoft's official documentation.

For more information on IE's URL limit, see Microsoft's official documentation.
