I’ve been limping along with Lookout because it beats the pants off of Outlook’s built-in search (or, more appropriately, “blind grope in the dark”). But I’ve run into some conflicts with Lookout because you have to hack a bit to get it to work.

Fortunately, I just found out about a couple of modified .dlls you can load which do away with the need for “major” hacking and seem to work just fine.

If I can spare some time, I’ll probably take a look at Xobni, though Lookout has pretty much taken care of my needs up until now.
