I have a cable modem and I recently configured my email through Earthlink to go to Outlook Express. For some reason I keep getting prompted to enter a password for dial-up. I have followed the directions from Earthlink to a T. However, at first I was able to RECEIVE messages but not send them. Nothing left my outbox. So I played around with it a little following Earthlink directions and now it's all screwed up. Any ideas? Not sure if I should be saying that I Broadband or that I"m running on a LAN connection or what because cable modem is not an option, although I tried to write in that I had Optimum and it didn't work.Nancy Shemo.....Sounds to me as if you havent got your E mail account properly configured.....Once you tell it your using lan you should never see the dialup request for username and password.......DIG out your mail setup info from your service provider and open outlook express
click on tools......then select accounts.......then click on the mail tab.....then click add and answer the questions and when FINISHED click ok ( I think) and set the new account as the default .
You will need to know      the POP 3 info and the SMPT info

hope this HELPS
