DBX File - opening and understanding

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

What is a DBX file?

Files that contain the .dbx file extension are used by the Microsoft Outlook Express email application. The DBX files contain folders that have been created by the Microsoft Outlook Express email program. These folders contain the email messages that are stored in a specific mailbox.

Each mailbox that is in a user's Outlook interface will have its own DBX file. For example, the Outlook "Inbox" will have a corresponding inbox.dbx file. The "Sent" mail folder will have a sent.dbx file. A DBX file will be assigned to each of the user's Outlook Express folders, including the custom folders that are created by the user. The DBX files can then be copied to another location so that a user can back up their email messages or transfer their emails to another computer when needed.
