We have a case where a spam email was sent to us and now we are rying to find out who actually opened / read it? We are able to easily find ou that it was delivered but unclear on how to identify if it was opened. Any help?

Hi, After viewing the problem, the issue seems to be related to email settings. If you are using Office in your environment, I suggest contacting Office forum to get more insights. http://social.technet.microsoft.com/Forums/en-US/outlook/threadsNiki Han TechNet Community Support
