I'm unable to archive 2 mailboxes.
It gives no error and it creates a PST file but that is always empty (32Kb, probably just the header).
All the other mailboxes, no problem.
The 2 mailboxes are also the largest (about 700 MB),
but diskspace shouldn't be the problem, 2.1 Gb available
in the exchange directory and 9 available in the archive directory.
We use Outlook 2000 with Exchange Server 2000.
