I am a fan of Mozilla’s Thunderbird email client and have used it on my work computer for years. Recently, however, my company installed an Exchange server to handle our email hosting (it had previously been through a third-party service). So, in order take advantage of the capabilities of our Exchange server, I had to migrate from Thunderbird to MS Outlook. In looking for an easy way to accomplish this, I found that I was not alone in the need to convert from Thunderbird to Outlook, and I was somewhat surprised that there seems to be no one-stop solution for this. I first had to convert Thunderbird’s mbox files to eml, and then use Outlook Import Wizard software to import the eml files into Outlook. Your software was easy to use and seemed to work fine.
