PST Corruption - mechanism and manifestation

[mrspeakers]

We've heard a lot about "1GB" being a limit for reliable operation of psts,
and we really need to know a) if this is true and b) what exactly is blowing
up, and why?

Anyone have some insight into what actually gets corrupted when a pst file
goes bad, and what the trigger for the corruption is (beside exceeding 2GB on
pre-2003 versions of Outlook)? Does 2003 eliminate (or significantly reduce)
this issue?

My personal experience shows reliable operation of ANSI PSTs up to 1.5 GB.

and b) what exactly is blowing up, and why?

That I don't know, but my speculation is that there's an integer overlow in
some pointer somewhere.

OL2003 in 2003 pst format eliminates the 2gb limit, I believe its in the
region of **gb, effectively unlimited however with a substantial pst you may
well suffer from 'info overload' ie too much info is untenable.
