We are a small company using windows xp pro on all computers, exchange 2003 and host our own e-mail. I have windows Vista at home and using web based exchange I can do everything but send e-mail. IE(7) hangs up and you have to restart it. The message is lost. Using my laptop with XP from home, web exchange works without any problems. Is there any special settings with Vista to make it work on my home desktop?
