Ugh. Ok, thanks all. That sucks. I'll probably do like Neil said and only
do the "problem" users. Seems like a potential security issue though, as a
malicious user with knowledge of the limitation could really kick the crap
out of your database if they were so inclined. Do newer versions of
Exchange correct this oversight? We're moving on up this year at some
point.

Thanks to all for the input.
