We have a new Exchange 2003 box, same domain as the current and we have successfully moved all the user mailboxes to the new box and it seems to be fine. However, there are some Public Mailboxes that I want to move and some that I do not. I have replicated all the ones that I want to move to the new box but if I dismount the Public store on the old box users start getting Outlook connection errors. The clients are all lookinig to the new box for the personal Exchange mailbox so I assume they are looking there for the Public mailboxes.
How do I get rid of old Public mailboxes? Delete them first on the old server?
