Usually your ISP help pages will have info on setting up Outlook Express,
with Outlook its basically the same proccess.
You need your;
User name (Your ISP user name)
Password (your email password)
pop server (incoming mail)
smtp server (Outgoing mail)
All the above are supplied by your ISP
Outlook 2000 is slightly different as you need initially to set up / install
in Internet Mode (This from recollection as its a long time ago)
If your ISP is a web based service, like Hotmail, there is a different
process.
