    Hi George,

    According to this list of outlook express error codes, that error code means:

    0x800CCC6B SMTP_551_USER_NOT_LOCAL User mailbox is known, but mailbox not on this server.

    Do you have a complete bounce message that can be used to help troubleshoot the problem?

    Also, Windows XP does not have support anymore from Microsoft. I strongly recommend that you update from XP to a modern operating system.
