Common Errors When Opening DBX Files in Outlook

1. “Outlook cannot open this file type”
This means you tried to open a raw DBX file. Outlook only opens PST and OST. Convert the DBX to PST first, then use File > Open & Export.

2. Folders empty after PST import
DBX files sometimes have a corrupted folder index. Run a DBX repair pass during conversion so the message tree rebuilds before the PST is written.

3. Conversion stops mid-folder
Large DBX files (over 2 GB) can hit the legacy file size limit. Split the source DBX into smaller chunks using Outlook Express, then convert each chunk separately.

4. Attachments missing in converted PST
Use a converter that preserves MIME parts. The 4n6 DBX Converter retains every attachment alongside its parent message.
