PSTs are BBBBAAAADDDDDD.
We (my company) has spent the bulk of the last year disabling PST and importing PSTs into a server based archive (Symantec Enterprise Vault) after having to search out and preserve PSTs and search them for legal discovery.
I should have some code that reads the user's messaging profile for PSTs and then robocopies them to a central store, but certainly nothing as sophisticated as Glenn's code.
