We use Exchange 2003 for OWA. Most users have Vista and a few use XP. They all have IE 7.
I have some users that need instructions on how to use OWA with Internet Explorer on Vista and XP. Most of the users are remote users. I don't have the time to create instructions on how to use the basic functions of OWA like, attaching a file, create an email, forward an email, check for the correct email address from the GAL, and use the Calendar.
I've searched the internet for books and documentation on how to do this. In a perfect world, I could travel down there and train them till they were proficient on it.
