Question: I have several users (user A) that need to be able to send messages on behalf of another user (user B) and I want any recipients of these messages to see the message as coming from "user A on behalf of user B".
I have tried the obvious methods:
1) Giving User A send on behalf permissions in the delivery options box of the Exchange General tab of User B's account properties.
2) Enabling delegate access from User B's mailbox in Outlook.
No matter what I do the messages appear to come from User B and I cannot get the "on behalf of" text to display in these messages.
