I was going to take a poke at the Auditing CD from the 2006 Exchange, so I put it in the CD drive.
Imagine my surprise when I get a message that the CD material only works with IE, and "to make IE as your default browser do...."
Ummmm I DON'T THINK SO.
Future training materials, etc. should work with both IE and FireFox.
I strongly agree.
I can think of no more certain turn-off than an IE only requirement (or an IE only requirement disguised as a mandatory ActiveX).
This is a technical audience. We all know better than to run IE. Even when we trust the source.
