YEsterday I had 2 people complain to me that they were not recieving emails from the outside. I went ahead and tested this from an outside email account and sure enough it never got to the user nor did i get a bounce back message. I have been checking the logs, but i dont know what to look for when people send messages from the outside. I went to Message tracking but it looks as though this only checks for things coming from the inside out. Is there another way i can looks to see if messages from certain outside email accounts ever made it to the exchange server?
