Huh?
I ran Outlook 98 at home, for free, didn't use Exchange, used an Internet POP3 and SMTP server. There was an Outlook98.exe program that I downloaded from Microsoft, and it installed Outlook 98 and IE 4.0, as far as I knew if Microsoft allowed me to download and install it, I had a right to use it? It was, at that time, as free as IE was, as far as I knew.
I am free now, to choose my own destiny.
