The error I receive is this: Task 'pop.att.yahoo.com - Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 530 authentication required - for help go to http://help.yahoo.com/sbc/dsl/mail/pop/pop-11.html' Obviously I have checked the email addresses...in fact, I cannot even send a test message from myself to myself! My att webmail works fine - so i have been sending messages that way - but this is exasperating having to use both the webmail and outlook!! ...and i've used outlook 2002 since 2002, so I have 7 years of business information on this that I do not want to particularly scrap. I don't know what to do - i've had tons of trouble with Outlook in the past 2 weeks and not sure what has caused it. HELP!1 person needs an answerI do too
