Tool to extract, recover and undelete e-mail messages from .dbx files
Platforms: Linux · Last verified September 6, 2026
UnDBX is a tool to extract, recover and undelete e-mail messages from MS Outlook Express .dbx files (or similar e-mail programs in MS Windows). Corrupted .dbx files can be parsed to try to recover messages from it. It can also try to undelete messages, not only from Deleted Items but also from fragments of deleted messages that were not overwritten.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
