I'd suggest if there is an "appointment" profile, that it be only for aptmts that aren't set to "free" time. IE. If I'm in a mtg in the ofc, I select "busy" and if I'm in an aptmt that's out of the office, and "out of the office" is selected, it should also treat it as if I'm busy in a mtg, but if I'm "free" (ie a scheduled item that doesn't tie me up) or if the aptmt is tentative, then the profile shouldn't change as if I'm in a mtg.
