BOX File

Did your computer fail to open a BOX file? We explain what they are used for and recommend software that we know can open or otherwise handle your .BOX files.

What is a BOX file?

A .BOX file is an Email Message file. Files that contain the .box file extension are most commonly used to store email messages. A variety of email applications use the .box file extension to store collections of email messages. These email messages can be opened individually by opening the contents of the BOX file.

The .mbox and .dbx file extensions have been replacing the BOX file format over time. Popular email programs that use the .box file extension include the Lotus Notes Mailbox, FoxMail, and Calypso email applications.
