I'm attempting to follow the Thunderbird directions (https://support.mozilla.org/en-US/kb/switching-thunderbird#w_switching-from-windows-mail-or-windows-live-mail-to-thunderbird) online for Converting from Windows Mail (Not Live Mail) to Thunderbird. I'm at the Import Step. The instructions say: "In Thunderbird, go to Tools | ImportExport | Import all messages from a directory | Also from its subdirectories." Under Tools, there is an Import, but no ImportExport. When the Import option is chosen, it does not allow for a directory location, only what to import (Eveything, Mail, Contacts, etc.) When choosing "Import Everything" and pressing "Next" nothing is in the list to import. The "Next" button does nothing and the Cancel Button cancels the entire Import. Can someone explain (or point to a current and accurate article on) how to import all mail (with local mailboxes and file structures kept intact). Thanks.
