Outlook Express Database

An Outlook Express Database (DBX) is used by Microsoft Outlook Express (distinct from Outlook) to store e-mail messages and folders.

File identification
Files begin with hex bytes.

This is followed by a class ID (CLSID) depending on whether the file contains messages or folders:


 * Message Database: 6F74FDC5-E366-11d1-9A4E-00C04FA309D4
 * Folder Database: 6F74FDC6-E366-11d1-9A4E-00C04FA309D4
