No, this is Windows Mail, and yes it is working with Windows 7 except it won't remain my default program. There must be something I can do in the registry? Windows 7 is running Winows Mail on here so there has to be a way to get it to recognize the program and make it default. It's taken a week to get this far - to get Windows Mail working. I prefer it because it comes with the calendar that actually has reminders.
