Hi mika,

No,it should not be any need to move the SystemMailbox{guid}. Remember, each MDB has its own GUID associated with a particular instance of SystemMailbox{guid}. You also need not to delete the SMTP mailbox and SystemMailbox mailbox, when trying to remove the mailbox store or uninstall the server.
