You know if your recall was successful if you get a message with the subject line "Message Recall Success."
When you recall an email, make sure to:
- 
                          Select Delete unread copies of this message or Delete unread copies and replace with a message. 
- 
                          Check the box for Tell me if recall succeeds or fails for each recipient. 
- 
                          Select OK.
