You do have to enable authentication when you are no longer on their network
(like you are from home).
Remove all the messages from your Outbox, enable the authentication option,
restart Outlook and try sending again.
Also, do you have a virus scanner installed which integrates itself with
Outlook? Uninstall this integration part of your virus scanner and try
again; you'd still be sufficiently protected by your on-access scanner part
of the virus scanner. For more details see;
