I have a friend who can't seem to stay organized. Stacks of paper litter her desk.
Old newspapers droop from chairs.
When she walks to the coffee pot, sticky notes go with her, attached to her shoes. Not if they won't use it. Perhaps the groupware isn't a good fit. I've linked you to several product reviews to help you make sure you have the right suite. The reviewers at Windows Sources seem especially impressed by the upcoming Outlook 97 from Microsoft, a desktop information manager and email client.
