[dazbc]

Hi
im the local lotus notes administrator for my company and use domino administrator. Recently I archived a few emails for an employee, but now if i go back into their archieve i cannot see any of the archive destination defaults eg(last modified).
And when i go to view the achieve settings and error msg appears "server error entry not found in index

Did anyone have a fix for this as we have the same problem and the server team just says that the emails are lost?
