You should reformat you Word document with commas between the various fields, thus:
Name1,Surname1,<e-mail address1>
Name2,Surname2,<e-mail address2>
which you can do via Find/Replace, replacing the spaces with commas, then save it as a plain text file with a .csv extension.
You can then use Outloook's import tools to add the data from the file as a batch. See:
