Nothing to do with this list, but why are you using .PST files? To see what
the top Exchange Consultants think of them, read the Appendix F of the FAQ
on Exchange at http://www.swinc.com/resource/exch_faq.htm

The active profile in the registry is backed up - its just that when you
come to restore the system there are about 3 extra very quick steps (copy
file from a to b) that need to be done - see the standard TSM restore
documentation for NT.

If the built-in re-try limits of TSM (try a few times for exclusive read,
try for shared read etc.) are not enough, then various Open File Agents are
available from third parties - BUT these are NOT recommended for all types
of open files (e.g. databases should be backed up using the correct Agents
that allow backups on-line).
