Outlook Express is the Internet e-mail and news reader included with Microsoft Internet Explorer version 4.0 and later. It was formerly called Internet Mail and News. While it shares the Outlook name, Outlook Express doesn't have the task- and contact-management capabilities of Microsoft Outlook, nor can it handle e-mail other than Internet mail. See OL2000 Differences Between Outlook and Outlook Express.

Outlook Express shares some components with Outlook, particularly those used for displaying HTML messages, handling S/MIME security and managing Internet mail accounts. For more details, see OL2000 Why Outlook 2000 Requires Outlook Express.
You can share information between the Outlook Contacts folder and the Windows Address Book in Outlook Express. See these MSKB articles:

Microsoft Outlook does not include an integrated newsreader for Internet newsgroups. (Opinion on whether this is good or bad is quite divided.) When you install Outlook 98 or above, Outlook Express is also installed and can handle all newsgroup functions using the Go, News menu. Or, you can just ignore OE and use some other newsreader.
The following add-ins are now available that allow you to read newsgroups in Outlook. If you use an Outlook 97/2002 *.pst with these add-ins, note that the pst size cannot exceed approximately 1.8 GB. Limit the number of groups you are subscribed and use autoarchive to keep the number of items per folder and pst size under control.
Note that because of limitation inherent in the MAPI transport, the features available in Outlook are limited compared to Outlook Express or another newsreader, including no headers-only option. These add-ins are slower than OE to collect posts and the two transports, NNTP for Outlook and Newshound, will work best with a few subscribed groups per server.
Fully-functional NNTP transport for the MAPI subsystem. Use it with Outlook 2000 (Corporate/Workgroup mode) and Outlook 2002/2003/2007 to read and post to UseNet servers. Provides support of MIME, RTF and HTML. Features include dial-up support and an articles cache to optimize the downloading from several accounts. Version 1.5. Supports Outlook 2007.
