- 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.
