firstly, once message submitted (and moved outbox) cannot touched - belongs spooler.

secondly, cannot send on behalf of arbitrary user. in case of exchange, set mailitem.sentonbehalfofname property name of exchange mailbox on behalf current user can send. in case of pop3/smtp accounts, set mailitem.sendusingaccount property 1 of accounts namespace.accounts collection.
