I have a customer who exported his calendar into a pst a few weeks
ago and it's size was 55 Meg. Last week he exported his calendar
(without removing any apts) and the size now is 29 Meg. Previous pst
files were also around 55 Meg, but his latest one is only 29 Meg.
There doesn't appear to be any loss of data (apts) in his calendar
but we don't know why the file size dropped so dramatically. Does
anyone know the cause of this?

I can think of a couple of causes but the file size you see is if very
little consequence. Don't think twice about it.

The more important issue is why your customer believes exporting to a PST is
ever a wise thing to de. Try to discourage that action, since it loses
data.
