Hi, Is it possible to recreate the user account? As you described your problem - It's a one user problem. Recreating the user account can solve the problem. Some highlights: When Exchange 2000 sends mail to a remote routing group, the message must travel through a connector. There are three different types of connectors: 1. Routing Group connector - Connects routing groups, so messages can be transferred between routing groups. 2. SMTP connector - Enables you to control the flow of messages between SMTP hosts. 3. X.400 connector - establish an X.400 messaging route between two routing groups or between a routing group and an X.400 system. Actually I don't think that you need the X.400. Look at: http://www.microsoft.com/technet/prodtechnol/exchange/2000/deploy/confea t/12x2kadc.mspx If you don't need the X.400, you can go to the user properties and in the e-mail address you can remove the X.400 from his e-mail address.

Internet Mail - Has the Exchange server as the bridgehead server and all outgoing is forwarded to my e-mail server which is the gateway. 2. Connector for MS SchedulePlus FreeBusy (Exchange) - 3. Connector for MS Mail (Exchange) Again, these were configured before I took over the server. John Tolmachoff Engineer/Consultant/Owner eServices For You
