The problem is not the client browser althought on the face of it, it appears to be.Regards + 0 Votes Client-side fix mosiers3 7 years ago Thanks!Since I posted my question earlier, I ran across the explanation, and a client-side workaround, as well as the Exchange server fix. Vista doesn't support a necessary ActiveX control. Simply selecting 'Basic' client in the Outlook 2003 sign-on screen gives you email edit capabilities, albeit with a rather plain interface.
