Issues completing migration to Exchange 2010

I have a client that has a lingering problem with a migration from Exchange 2003 to 2010 (both servers are still on the domain but the 03 server is going to fail imminently so i want to 'retire' it cleanly as a matter of urgency) -- two issues, 1. some migrated mailboxes are still showing as 'legacy' - their Properties show's they're connected to the new Mailbox Store (see attached) - their Outlook clients also show as being connected to the new store.

2. The second problem is one users Change Request failed and although I've cancelled the failed request the option to request a Change Request is no longer available for this user only, plus their mailbox properties shows as still being connected to the old Mailbox Store (see attached) as does outlook.

Any suggestions how to resolve these two problems please?
