A real estate agent in my office bought a mac recently. She will use the mac at home and her windows pc at the office (because a real estate site we use doesn't support ANY browser besides IE). She uses outlook express as her mail client. Is there anyway to sync outlook express with Apple's Mail app so that when she read's an email in one program, say outlook, it will show up as "read" when she see's it in Apple Mail? I'm aware that Apple's new MobileMe service will do this, but I don't think she'll want to pay for that service every year JUST for that feature and I'm not sure she'd be able to use her current email address with that service (and she has to keep her email address as it is for business reasons). Can anyone help?
