Hi,

The setup is " outlook 2003 / ex2k3 ". This error message comes for a user
and when he send a email to another specific user. He can send emails to all
others absolutely fine.

This message could not be sent. Try sending the message again later, or
contact your network administrator. Error is [0x80004005-00000000-00000000].
