outlook express vs microsoft outlook

[Joyce]

I recently purchased my new dell computer with microsoft
XP. I now have transferred everything from my old
windows 98 computer to this one. I have both Outlook
Express 6 program and Microsoft Outlook. I enjoy the
calendar on Microsoft Outlook, but I cannot get my email
there. I get my email from outlook express.

What is the difference - besides the calendar? Can
someone help me?

Thank you.
