My Outlook 2010 has suddenly decided not to allow emails to be sent. I am receiving fine but when I go to send an email it attempts for some reason to try to send 2 emails, one of which isnt there!!. This is then causing a time out error message saying that there is nor reply from the server. I have been onto my ISP and all settings are o.k. My Blackberry is also sending and recieving ok. It is as if there is an email stuck in Outlook that I cannot find and is obviously quite large causing the time out. On occasions, instead of reading sending mail, it will read preparing to send mail .... then nothing happens.
Can anyone help please as I am losing valuable work through this.
