Outlook 2003 0x800ccc78

[Anthony Williams]

When I send emails outlook 2003 says that there was a
send error 0x800cc78 and that I should check my email
address in account properties but it is correct the
emails are being sent but this error message keeps coming
up.

Can any help?

Hi Anthony,

From MSDN:

0x800CCC78 SMTP_REJECTED_SENDER Unknown sender. This is caused by
having the incorrect e-mail address

in the Reply-To field.

Type 0x800CCC78 in search at Microsoft site, and you'll find a few
possible reasons. E.g., SMTP server require authorization and answer
"access denied" or "no relay" to all unauthorized users.
