Conversion scope
DBX file is one Outlook Express mail folder and few current programs open it. Renaming the file or copying it into Outlook gives nothing to open. DBX to PST software decodes the folder on Windows and rebuilds its messages inside a PST, with your DBX left as it was.

4One Outlook Express folder per DBX file
FileInfo DBX page says a DBX file is an Outlook Express mail folder, like Inbox.dbx or Sent Items.dbx, with a separate Folders.dbx as index. It says Outlook Express is discontinued and current Outlook has no import for that format. Corbett opens the files on Windows and builds a PST that Outlook opens like any data file.
Related pages include PST Converter, EML Converter, MBOX Converter and DBX Converter. Other mail files sit on email converter tool page.
Core features
Five screens of Corbett DBX to PST utility software, in conversion order.
Source files
Select Open, then Email Data Files and add your DBX files. DBX to PST converter brings your mail into its panel and no Outlook Express is needed.
Spare PCs with no Outlook still work. DBX to PST conversion software opens your files and leaves them as they were.
Batch loading
Select Choose Files for one DBX file or a few. Select Choose Folders to load an entire directory of DBX files in one step.
Loaded mail appears in one tree with a checkbox beside every item so Corbett handles many DBX files in a single session. No file size limit applies.
Message preview
Click any message and a reading pane opens beside five analysis views. Use them to confirm correct mail before DBX to PST conversion starts.
Content shows the email body. Message header lists From, To, Subject and Date. Properties reports message data, while hex and raw message views show the stored mail.
Output formats
Select PST for Outlook. That same load can export to EML or MBOX for email files and PDF, HTML, TXT or CSV for documents. Export menu lists Gmail, Office 365, IMAP and Thunderbird for sending mail into an account.
Search by keyword first, then save only matched items. Quick search highlights hits in yellow and Advance search checks every field or only name, subject, To, Cc and content.
Export options
Switch on open folder after export, leave out greyed out folders, create empty folders and include email headers. For PST output, create an individual PST file for every folder so every PST stays small and quick to open.
Select Browse to choose a destination, then Save. Live progress shows every folder as it converts. Need other formats? Open DBX Converter.
Working process
Four steps take your DBX files to a PST. Try them on a few files in free demo first.
Add your DBX files
Start DBX to PST software, select Open, then Email Data Files and add your DBX files. Select Choose Files for one file or Choose Folders for many.
Preview and select mail
Your DBX folders load as one tree. Click any email to preview it, tick what you need and search by keyword to trim your DBX to PST conversion.
Choose your output
Select Export and choose PST. EML, MBOX, PDF, HTML, TXT and CSV sit in the same menu for other jobs.
Save your converted mail
Set options, select Browse for a folder and press Save. Live progress shows every folder and Open Folder takes you to your PST.

| Outlook Express installed | Not needed | Files open on a modern Windows PC with no old mail program |

Outlook or tool
Outlook Express can export mail to Outlook when both programs sit on one old PC. Most people no longer have that setup. Here is where the free route stops.
| Task | Manual export | DBX to PST Converter |
|---|---|---|
| Cost | Free | From $99 one time |
| Few folders | Export wizard works | Works too |
| Folders of DBX files | Folder by folder | One batch of files or folders |
| Outlook Express and Outlook | Both must be installed | Neither required |
| Output formats | PST only | PST, EML, MBOX, PDF, HTML, TXT and CSV |
| Data extraction | Copy by hand | Addresses, phone numbers and attachments |
| Filters | Folder search only | Date, time, To, From, size and name |
| File names | Fixed by the program | Named by From, To, Date or Subject |
For one folder on an old PC with both programs, the free route does the job.

Before conversion
Three short checks keep your DBX to PST conversion clean.
Copy DBX files off the old PC
FileInfo DBX page says a DBX file holds one mailbox, like Inbox.dbx. Copy them into one plain folder so DBX to PST converter opens them together.
Leave out Folders.dbx
Folders.dbx is the index and holds no messages. Load Inbox.dbx, Sent Items.dbx and your other mail files instead.
Check free disk space
PST can take more room than your DBX files. Select an output drive with plenty of space.
Opening the finished PST is covered in Open DBX file in Outlook and Windows Live Mail to Outlook.
Best practice
Your PST only helps if your mail arrives in full. Four habits keep your data safe through it.
Backup first
Copy your original DBX folder before DBX to PST conversion starts. Keep 3 copies on 2 types of media with 1 copy off site.
Start with one folder
Convert one small DBX file to PST with Corbett and open a few messages in Outlook. Catch a wrong setting before a large job.
Check the count
Compare folder counts from your old mail program with the folders in your PST before you close your DBX to PST job.
Keep originals until checked
Store your source DBX files until counts match. Delete them only after you open the PST in Outlook.
