I deleted Microsoft Communities as suggested but this has not cured the problem for some reason. I have also noticed something else. If I click 'send & receive' when there is nothing in the Outbox, the message comes up, 'connecting to the server' and it behaves much as I would expect. However, if I compose a message and send it to the Outbox by clicking 'send' on the message, then click 'send & receive', nothing happens. The message does not get sent and there is no message about connecting to the server.
