Simon,

	No, users see the folders, just not old messages. For most (all?) 
INBOXes but my own, new messages started arriving as 1. and continued 
from there. Users can see the new mail, but not the old. This makes me 
think it's not an internal permissions problem, because they see the 
mailboxes and (some) mail in them. All file permissions I checked appear 
correct

	"reconstruct -rfx" doesn't help. Is there anything else to try?

Thanks,

Chris
