Why has my Outlook stopped sending my mail???

[leigh.redman]

I have been using Outlook 2003 for ages to access my BtInternet mail,
and now all of a sudden i am being asked to confirm my network password
over and over, and regardless it still will not send my mail.

I have been on to Yahoo and it sends ok.

I have removed the account and reset it.

I have checked and confirmed the settings about a million times .

But it is still asking me.

I have a feeling it is a problem with the program (or been hit with a
virus of some kind), I did uninstal it and re-instaled, but there must
be some settings it does not remove fully because when i re-installed
my history was still there....

help please.......
