You don't need to download Outlook Express. If you have Windows OS, Outlook Express is already installed as a Windows Component. If you would like to set it up for use as the default mail program, here is the easiest way:
Right click on Start> Explore> Programs> Outlook Express> find the msimn.exe file on the right screen and double-click to open:
Once open, you will need to put your ISP server in here:
Open OE> Tools> Accounts> Mail> Properties> Server tab>> enter the POP3 and SMTP servers for your ISP, Account name and password (phone call to ISP will do it).
Once done: Open IE> Tools> Internet Options> Programs tab> set Outlook Express as the default email. Check 'IE should check to see if it is the default email'> Check now> answer Yes
When it has been set up, it's ready to use. It's already on the computer so downloading isn't needed.
If you would like to create a shortcut for OE to put in the Quick Launch Toolbar:
When you're in windows explorer> right click on msimn.exe> Send to> Desktop to create a shortcut.
Right click on the Taskbar> uncheck 'lock the Taskbar'> drag the OE shortcut into QL> re-lock the Taskbar.
