Outlook 2007 wont send email

[Davidifl]

Hi

Outlook 2007 has today stopped sending email.

It always fails, saying “SMTP server time-out”

I have made NO changes to ANY settings, I have not changed or upgraded firewall, and only routine update to AVG which happens every day. I am running Vista Ultimate.

It has worked fine for several months, but today - Zip

I have many other computers at this location, and they all continue to work perfectly, sending and receiving mail using exactly the same connection and ISP.

So... suddenly Outlook 2007 will no longer send mail.

It still receives e-mail normally

Any help please?
