Well, for older versions of Exchange, the trouble starts when you hit
about 800MB -- that's when Outlook takes forever to open and load your
mail folders. Then it doesn't warn you (at least it didn't for me) when
you have exceeded 2GB which is the upper limit of a PST file (IIRC) for
the older version of Exchange I was using, and then the corruption
starts, and the hair-pulling. All it takes is for someone to send you a
huge file just as you are approaching the threshold, to completely hose
all your emails.

Unfortunately, this is the one function that a lot of Exchange refugees
want that they cannot get with standard Linux offerings. A while back I
noticed that there was at least one open source project that was
attempting to provide this feature, but I cannot recall the name now. I
think Sun Calendar Server can provide the functionality, but I'm not too
sure of that either.

Anyway, what the study shows to me is that a heartening number of admins
have made a sensible choice.
