OAB Errors After Transition to Exchange 2007

We are getting the following error message when using Outlook 2003 and Outlook 2007 Clients

08:42:22 Synchronizer Version 12.0.6211
08:42:22 Synchronizing Mailbox 'Alistair Gray'
08:42:22 Done
08:43:25 Microsoft Exchange offline address book

We have just completed the Exchange transition from Exchange 2003 to Exchange 2007. We have removed the temporary connectors between the 2003 and 2007 servers. Our first Exchange Server on 2003 is now switched off - And we get the sync message above! We have not replicated the system folders and now we have deleted the temporary connector between the 2 servers. Do we still need to replicate these OAB  2 / OAB 3 / OAB 4 system folders before the messages dissappear? Can we still replicate if we switch the Exchange 2003 back on (even although we have deleted the Transition Connectors?

Can we fix the OAB issue in Exchange 2007 alone, assuming that the Exchange 2003 Server will be removed from the organisation. Can we still fix this issue in Exchange 2007 alone or do we have to switch the original server back on and recover somehow from there?
