c) the issue we ran into with outlook 2007 and online mode was that using the instant search feature yielded inconsistent results. also when opening advanced find the filters were grayed out. we ended up having to install windows desktop search on the golden image so to alleviate our the search problems. we receieved many complaints about that during our initial rollout so hopefully this will save you the headache. if you do a google search for outlook 2007 advanced find you'll see what i'm talking about.
Could you elaborate on this? What OS are you running and what do you mean by inconsistent results.
