I'm sorry I have never heard of anyone trying this without an exchange server involved. I think the principle here is to share your calendar information with users on different computers. It wouldn't make much since to need to communicate free/busy time with different accounts in the same outlook so it is designed to publish the information somewhere whether it be a file, server, or the internet. That being said it should still be possible to do it. Read this article for more info on the way Free/Busy is intended to work.

Free/Busy information is stored on the server and cannot be cached. Make sure Outlook is "Connected" and not "Offline". Try running Outlook in non-cache mode to see if that helps.
If that doesn't work then I am out of suggestions at the moment, but I will keep playing with it to see if I can replicate your problem and find a fix.

Thanks for the links anyway, I am likely giving up on this for now, I got around it for what I needed it and that's enough time spent.

But if you still find anything post it here please, it will send me a message to alert me, I would like to know it, I just can't spend any more time on this.
