This is for exchange server 2007.  Any ideas on troubleshooting please?  This is very urgent.  Thanks.

This is not the best site for urgent queries. If you have an urgent query call Microsoft.

Has it ever worked? If you send a message from OWA does that work?

no OWA doesn't work..

and the 2000 exchange server was working fine, and the introduction of 2007 has screwed up everything.  Now NO ONE can send out mail....

That is a bit different.
If the installation of E2007 caused the problem then remove it. Use Add/Remove programs and get the product out. Then get E2000 to work correctly before you carry on further.
