… its a nightmare.
I tried this aaprently famous and proved option, but it didn’t work for me.
Had to download Eudora, import some non-extension thunderbird files into it. Open Outlook Express, import from Eudora through some work around way (selecting import from Netscape using the pref.js file from Thunderbird). Then import from Outlook Express into Outlook 2003.
Here are the steps I took:
1. Read EAFiedler’s reply to main post.
2. Follow these instructions after.
