Why doesn't my e-mail get sent when I press the send button?

[dstaiman]

When I try to send a e-mail in Microsoft Outlook by pressing the send button
, the e-mail is placed in the outbox folder and does not get sent. To send
it, I have to press the send/receive button. My e-mail is set up to
send/receive messages every 5 minutes and that also does not work. I can get
mye-mails by depressing the send/receive button.

You first: state your Outlook version.
