"Groupwise Error 8200" when restoring e-mail.

I have restored my POA to the network as I need to restore a few emails i
deleted from last week, Have filled out the appropriate fields for
Restore Area Management pointing to the backed up POA - and I have
successfully opend my backup mailbox.

However when i try to "Right-Click" and "Restore" a message I get an
Error 8200 messages "GroupWise cannot open the post office files"

I have tried mailbox maintenance etc and still have no luck - the rights
to these files/locations are ok as I am logged in as admin at this moment.

Anybody got any ideas ?
