Check in the registry for HKEY_CLASSES_ROOT/Outlook.Application - this will tell you if it is available. You should then be able to hunt the links in the registry for the post office location and then check if that exists.

As for checking if you're connected to the network, look at the API calls WNET... (WNetGetConnection, I think is one you could use).
