Export Email from Thunderbird to MS OutlookExpress

Normally Thunderbird support import of Email from OUTLOOK but it don't have option for Exporting as of now. There is no direct option to export to MS OUTLOOK formatThis process is a bit more complex . Outlook doesn’t directly import Thunderbirds email, however with the right tools, and some time, it can be done.The first thing you’ll need is a program called IMAPSize. It’s a free Windows application that has a built in tool called mbox2eml. This handy program is used to convert Thunderbird’s mbox email files into eml files. The mbox files are found in your Thunderbirds profile folder (usually in the mail -> local folders). If you don’t see any files with the extension mbox, then it’s the ones without an extension.

The downside here is that each folder you have in Thunderbird is a seperate mbox file. You have to convert each one. Anything in a sub folder will have to be converted too and you may start to loose your folder structure. Oh well, you can always put it back together later.

Once everything is in eml format, you must now startup Outlook Express! That’s right, Express. No need to setup an email account in there, but you should setup all your folders to mirror what you had in Thunderbird. Then, open the folders on your computer that were created from the mbox2email tool and drag the individual eml files into the corresponding Outlook Express folders. You can drag and drop as many eml files as you want, but you can’t drag in a folder. Once you’ve copied all your emails into Outlook Express, you can now import them into Outlook.Startup Outlook, create your profile and once that’s all setup, go to Import/Export, import from another application and choose Outlook Express.
