This is urgent as i need a message that has been sent to me.
When I press Send/Receive it just hangs waiting to send, there is one message in the outbox and can see that there are 18 messages to come in.
I think it might be the message that it is trying to send, it says it hasnt been sent yet, but the person has received 15 copies of it so far, so i think it is stuck in the outbox. I have tried to delete this message from the outbox but get the following error:
"The messaging interface has returned an unknown error. If the Problem persists, restart Outlook."
I have restarted outlook, restarted my PC, and used detect and repair in the help menu and nothing works.
