OUTLOOK EXPRESS
Outlook Express is a multi-purpose mail, news and directory service client that comes as part of most Microsoft operating systems.
There is a lot wrong with OE; very few experienced Internet users employ it. However, it is the most commonly used client, and for this reason we must assume it to be the client used on most people's computers.
We can forget "directory services". I know of nobody who uses them. News we will talk about in another session. Today, we will concentrate on setting up accounts and sending and receiving e-mails.
