send message will not send

[carolyn]

I have one message in my outbox that will not send. Outlook attempts to send
it each time I send out but is unable to do so with the one message. I get
aneerror message ox8004210B operation timed out waiting for a response from
the sending STMP server.

Do you have more than one account? Is it a message you composed afresh or
is it a reply to a message? What version of Outlook? What account type(s)?
