Here is a screenshot of my email client which show all his emails (in the red rectangle), after I added his mailbox to my email client. What you see on the left navigation pane shows my folder list. I want to be able to open up his inbox so that I can see his folder list as well. This is for the purpose of troubleshooting because I do not have the leisure of doing a remote session with him all the time as he is a very busy guy. My email client is version 2013, while his is Outlook 2007.
