Finally got my problem of sending mails via Outlook sorted. I followed Sky Goats advice and visited the Google help pages. I have MS Auto Update on for my PC, so assumed it d/l everything MS. It didn't for me. When I checked for updates, it said I needed Office SP3 (50mb). As soon as I d/l the pack and rebooted. I can now send and receive OK!

Result.

Thanks everyone.
