Hi,
I recently had to reinstall my desktop due to a serious virus problem. I reinstalled MS-Outlook and I am having an unusual problem. My outgoing messages don't get sent. Instead, I receive a message from "System Administrator". The message reads: "Your message did not reach some or all of the intended recipients. ..... Relay access denied"
Any ideas?

Thanks in advance for your help

Check your SMTP settings... you might need to check My SMTP server requires authentication.
