I can access Exchange at the address
https://mail.[username]/exchange/ (which always comes up with annoying certificate messges - why don't they fix it?). With Windows XP it worked fine. Some computers ask permission to run an app. Under Windows 7 Exchange will open so I can view
emails, but when I try to reply, the return screen is blanked out and it will not work. Presumably it needs an app to run but Windows 7 does not even offer the option of running it.
