Which version of Outlook are you using?
Which mail account type are you using?

These issues are usually caused by an add-in that you have installed.

Do you have a virus scanner installed which integrates itself with Outlook?
Uninstall this integration part of your virus scanner and try again; you
would
still be sufficiently protected by your on-access scanner part of the virus
scanner. For more details see;

To troubleshoot other add-ins, you can disable them all and see if it works
now. If so, you can enable them one-by-one to find the culprit.

When I compose an email and click "Send" it appears in the Out box with an
opened envelope icon. The message goes no further. If I then open the
message in the Outbox and forward it to the same addressee and then press
Send it drops back into the Outbox, this time with a closed envelope icon,
and pressing Send again sends it on its way. Why do I have to go through
this forwarding routine? This problem has only just happened, and has
affected two of my computers at about the same time, which suggests a
software update issue.
