It's not supported and not guaranteed, but it just might work. If not, you can buy a more current version of MS Outlook, if you prefer that.
If you google MIGRATE THUNDERBIRD TO OUTLOOK you'll discover that by far the easiest way to do so is to buy a third party program and use that.

Can MS Office XP Pro be compatible with Win 7 Home Premium? My refurbished IBM ThinkPad came with the Prod. Suite of Apache OpenOffice 4, but I want to replace the Mozilla T-Bird 24.5 with Outlook XP as my default client.
If that can be done, how can I move all saved email from T-Bird to Outlook?
