I am looking for a way to search from Exchange to find all mail sent from my users to a single domain?

You could use Message Tracking, assuming it's enabled on all servers.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Message Tracking which can be found in EMC under toolbox is the tool you need. There you can choose approperiatte Event ID and recipientsWith kind regards Krystian Zieja http://www.projectnenvision.com Follow me on twitter My Blog
