Please forgive me if this problem has been mentioned elsewhere - I've searched but I cannot find a similar thread.

I am using Outlook 2010 with Win 7 Home Premium; my main email account is a hotmail account. Everything works just fine - except recently when I close Outlook I get a message saying that there are unsent messages in my Outbox - but there aren't.

Could anyone suggest how I can get rid of this annoying message?

Thanks in anticipation.
