query - outlook express vs microsoft outlook

Email Query.

Microsoft Outlook Vs
Outlook Express

Can anyone please tell me which email account (above) I should utilise and
pros and cons.
I find that my old MO acct. has more features such as, being able to
"retrieve emails" etc. Maybe I am not using OE to full advantage.

I have both on the go. The default being OE.
As I have just changed from 'dial up' (using MO) to
OE now on Bigpond cable, which is much faster and has other benefits.

Any advice on these two email accts would be great.
(currently I am trying to retrieve an email I sent using OE and I can not
through the help menu work out how to do)

Thanks in anticipation
