My Mac Book is death, so I need to change the emails to my PC windows-based. So I've installed Thunderbird (TB) in my pc with sucess. Now I need to import the mailboxes that I have in a pen-drive into the TB, on my pc. I've look in the web but I can't find any instruction that can solve my problem. I also try to install TB in the mac, while is still working, but the TB version is nor supported by the old mac system. Can any one help me. I really need to keep the Archives email files. Thank you.
