Address book cleanup and how to transfer Outlook contacts to Thunderbird?

here are my thoughts: - delete all contacts in addressbook - manually create one or two valid accounts - export a csv from thunderbird, this gives you a template so that you know how thunderbird wants csv organized. - if you have a spreadsheet program, that is easiest way to view the layout. remember, the top row usually as names of the columns - now, load your csv into the spreadsheet and modify as necessary to mirror the thunderbird layout, keeping the same top row - now, save the updated csv and import that, and then view the addressbook to verify contents
