In my setup there exist user1, ..., [email protected]. Mail for example.com is handled by Exchange 2010 and all the users user Outlook 2010. There also exists a Standard Distribution list named [email protected]. Is it possible to have some of the users being able to send email with [email protected] as the sender address? Can the sender's GECOS be different too when this happens so that the recipient sees "Offices of Example.com" instead of "User Name X"?
Sometimes the secretaries need to send stuff as "the office" and not as theirselves ...
You can use the GrantSendOnBehalfTo Paramenter so that a particular user can send on behalf that distribution list
