Please could someone help. I was running Thunderbird on my old hard drive, but the drive broke but luckily I have managed to retrieve most of the the data from it, including the Thunderbird folder. I now need to import all the emails from the old Thunderbird folders into the Windows Live Mail program that I now have running on my new Windows 10 installation on a new hard drive. I would also like to retrieve all my address book if possible. The Windows Live Mail only gives me options to import from Outlook Express, Mail or Live Mail installations and no options for Thunderbird.

I thought that if I installed Thunderbird onto the new drive I could then export all the emails to Windows Live Mail, but I am unable to get the new installation of Thunderbird to retrieve all the old emails from the old backup folder, so I am now completely stuck. I desperately need all my old emails, so any help will be massively appreciated.
