Unfortunately, no it didn't sort it - the problem came back...
I have finally resolved it. It was 4x Read Receipts (originally 5x) it was trying to send out on an email account I no longer had access to..

Read receipts are invisible to the user, once they click agreeing for them to be sent. So no obvious way to delete them in Outlook, except using the above process.
