i have exchange 2003. I use cached exchange mode. I have granted user1 permission to open user2 mailbox and send as permission. Is their any way when user1 replies to an email for user2 for a copy of the sent item to be delivered to user2 sent box? Curently it only goes to sentbox for user1. second part of question is now that user1 has send as permission how does user1 send a new email on behalf of user2?
