There are 2 systems in my computer. The desktop PC is running Windows XP and laptop is working with Windows 7. Right now I am demanding to import an address book from Windows XP to thunderbird in Windows 7. The address book (wab) is Stored in an usb storage device and therefore the import attribute of thunderbird cannot discover it. Up to now the merely thing that I have attempted is converting the wab file to csv and attempted to import that into thunderbird except it does not function at all. Do you have any suggestion over this?
