Synchronized Offline PST Files

You know what I think would be great? Being able to access my complete Outlook Inbox mail, settings, preferences and folders from any internet connection where I’ve got access to Outlook. That’s not just it though, I want Outlook to run as normal when I’m sitting in front of my own computer working as well.

I’d envision something along the lines of your local .pst file being uploaded to the Office Live server somewhere and synchronizing with your local file whenever a network connection is present. This would allow me to access mail I’ve download on my local machine from anywhere if I’m away from that machine and doing work somewhere else.

The settings in Outlook for data file management would allow me to specify a remote location to store the file and it’s synchronization settings as well.

Why can’t that type of functionality be the sort of thing you get with an Office Live account?
