Scenario: Windows 2003 Server Standard + Exchange Server 2003 Standard. I need to create a mailbox without a user. The owner of the mailbox would be another user (with its own mailbox) and he has to send messages with the mailbox address as sender (the messages cannot be send as "in bear of" in which the user´s address appears as the originator). Can anybody help me? Thanks a lot. Antonio V., from Madrid (Spain). .
