Hi
I have an SBS 2003 server with exchange 2003, an Exchange 2007 server and now an Exchange 2010 server. The 2010 is a fresh install to replace the 2007 server, once I have uninstalled 2007 that machine will be switched off, then I will uninstall the 2003 server (I plan to do the 2003 last as it's an SBS server that will be decommissioned soon and is our PDC). But I am getting an failure when I run the uninstall saying that:
Mailbox
Role Prerequisites
Failed
Error:

one or more mailboxes. To get a list of all mailboxes in this database, run the
command Get-Mailbox -Database <Database ID>. To disable a mailbox so that
you can delete the mailbox database, run the command Disable-Mailbox

After digging I found that there was a mailbox still in the datastore under the name administrator, trying to move this mailbox to the new server throws up a new error:
Summary: 1 item(s). 0 succeeded, 1 failed.

Administrator
Failed
Error:
Error was found for Administrator (Administrator@domain) because: Error occurred in the step: Opening destination mailbox. Failed to open mailbox with error: An unknown error has occurred., error code: -1056749262
Exchange Management Shell command attempted:
'domain/Users/Administrator' | move-mailbox -BadItemLimit '100000' -TargetDatabase 'Mailbox Database 0409936941'
Elapsed Time: 00:00:12
and the move process fails...I have run the Exchange BPA connectivity tests and all seems ok, so I am a bit stuck as to what to do next. We only use the exchange server to create mailboxes which then are migrated to O365 as we are have federated our domain for SSO.
As part of the removal process I deleted any routing group connectors on the 2007 server and have switched off all Exchange services on the SBS 2003 server, but I don't see how this would effect what I am doing?
