Opening DBX files

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

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
