We are using Exchange 2007 SP1, our users can send on behalf of a mailbox but the recipient does not see "Sent on Behalf of". I've tried using the Send-as permission, the Send-on-behalf-of, and making the person a Delegate (each permission was used individually not combined) and still no luck. Is this possible with 07? Thanks Scott

I am having the same problems and would also like to know if this is possible in Exchange 2007.Thanks in advance
