The Live Mesh for Mobile client only works on Windows Mobile phones. And, it isn't meant for synchronizing data with Outlook. It is meant for synchronizing data - documents and other files, not contacts and messages.
You may want to look at Windows Live for Mobile to access your Windows Live contacts.

To sync Outlook data on a PC with a mobile device, you'd need ActiveSync or Windows Mobile Device Center, but that will only work with a phone running Windows Mobile. There are 3rd party sync programs that you can use to sync other phones with Oulook data.
I can't answer regarding the SpeakOut network, sinc I have no idea what that is.
