Visual Basic: MAPI Controls
Returns the mail address of the originator of the currently indexed message. This property is not available at design time and is read-only at run time. The messaging system sets this property for you when sending a message.
The MsgOrigAddress property syntax has these parts:
|object||An object expression that evaluates to an object in the Applies To list.|
The value of MsgOrigAddress depends on the currently indexed message as selected by the MsgIndex property. The value is null in the compose buffer.
