Most likely that you have a corrupt address in the DL.
Are all your other messages sent correctly?

Hi,
I am a new user of Outlook 2000. I have set up a distribution list but
when
I tried to send an email, I get a System Administrator message that says
No
transport provider was available for delivery to this recipient. What
does
that mean?

Thanks--
