You will need a news reader, such as FreeAgent - I don't think that Outlook it self will read news (but I may be wrong - I only use it as a PIM, not a mailer). click here for a selection (including FreeAgent).
In IE you click tools and select mail and news/ read news. You may need to subscribe but if you choose to use Outlook as the default mail program all settings will be there. It will ask to import the settings from the other program you have been using.
