I had a very good experience with Outlook Import Wizard v.3 And the price I paid was very good value for the time and hassle I saved. I had a thumb drive with the .dbx files from the Outlook Express v.6 on another system. I turned them into .eml files – more on that below – and used Outlook Import to bring them into Outlook 2007. After successful import, I found the same folder structure in Outlook that I had in my working export files, with all converted emails intact…
I also used a free program to convert .dbx files to .eml files. It is dbxconv.exe. The dbxconv converted 10,616 emails in just a few minutes and your program brought them into the correct file structure in Outlook in about 12 minutes. Compare that to the several hours required by an older computer running XP and Outlook Express to export to .dbx files in the proper directory tree.
