1.3.3 Acting on Behalf of a Delegator

When the delegate sends messages on behalf of the delegator, the delegate's client sets properties on the Message object to indicate that the message is being sent on behalf of the delegator. The server then validates that the delegate has the appropriate permission to send on behalf of the delegator.

It is also possible for the delegate to receive meeting-related objects on behalf of the delegator. These objects can be acted on only if the delegate has the appropriate permission to the delegator's Calendar special folder and permission to send mail on behalf of the delegator. Both of these permissions are required to properly process and respond to meeting-related objects.
