Bingo. Good eye, Sue.

I finally got a chance to log into a PST file profile (on Outlook 2007) and
there was no PR_LAST_MODIFICATION_TIME property there in any of the folders.
I'm surprised, but it seems that property is store provider dependent and
not always there.

FWIW, I don't see PR_LAST_MODIFICATION_TIME on any .pst folders. Could that
be the issue?
