Convert Outlook Express Mails To MBOX Format
When I set up the laptop for my brother I decided to use Ubuntu instead of Windows. But as he used to have Windows installed, the mail program he used was Outlook Express. So I was looking for a way to convert his .dbx mail folders to the MBOX format (which Thunderbird can read) under Ubuntu.
I found the tool DbxConv which runs under wine.
And here is how to use it:
wine /path/to/DbxConv.exe "FolderName.dbx"
This gets you a file called “FolderName.mbx” which you can open in Thunderbird and for example copy via IMAP to Gmail.
