I have a scenario where I am using Outlook 2003 for my email accounts.
We have SBC Yahoo for internet access.
I am getting the following errors but emails do eventually leave the outbox after a few minutes.
Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 553 From: address not verified;
(it has nothing to do with being case sensitive)
I am logging into the outgoing email server for yahoo to send email from a differerent domain. (its the only way I could get it to work.
Currently using ports 110 & 25 and Outgoing server requires authentication using the login for the SBC Yahoo router.
