Sending errors
 

I have recently changed to Office 2007 beta 2 and now I cant send emails I
keep getting the following error message

Sending' reported error (0x80042109) : 'Outlook cannot connect to your
outgoing (SMTP) e-mail server. If you continue to receive this message,
contact your server administrator or Internet service provider (ISP).'

Any ideas? I am using XP home if that useful.
