Exchange 2010 Management Console connecting to a decommisioned server

You may find that the Exchange Management Console still attempts to connect to a previous Exchange 2010 server when opening, this can be resolved by navigating to the "HKCU\SOFTWARE\Microsoft\ExchangeServer\v14\AdminTools" registry key and deleting the NodeStructureSettings value.

Once deleted start the Exchange Management Console and it should automatically detect the On-Premises organisation and this time connect to a live server.
