I am not exactly sure what you mean by "I could point Word & Excel to it to e-mail documents & spreadsheets"
If you mean which program launches when you click on an e-mail link in one of those applications, you will want to set Windows Live Mail as your default e-mail program, which is an option available through the Control Panel.
When I was using Outlook Express, I could point Word & Excel to it to e-mail documents & spreadsheets. Since I have installed Windows Live Mail, all e-mails go to Outlook, which I have never initialized.
Does anyone know how to link Office applications & Live Mail? I've looked everywhere I could think of with no joy.
I use a Dell Inspiron 1900 with Windows X.
