After some more frustration, I have no choice but to post again. Here's my free/busy options window:
And I see no files created, the folder is empty and everything else is the same. What am I doing wrong? Can't people at the same computer share their free/busy info without using a server or the internet at all?
I can potentially see another issue because other profiles have to use the same publishing path which wouldn't be the case if they were on another computer. Shouldn't they have their own .vfb file to save their info to?
