Send error in Outlook 2007

[TimD]

I am getting the following message:

Task '[email protected] - Sending' reported error (0x80070057) : 'Could
not complete the operation. One or more parameter values are not valid.'

Although messages are shown as sent they are not going? Any suggestions?

You could try logging the SMTP conversation to see what's going on behind the
scenes. Take a look at this article for info on logging:
