I was just assigned management of our Exchange Servers. The person who installed and configured our Exchange 2010 Servers did not set up permissions correctly. I noticed that anyone within the organization can open a users mailbox without them being assigned. This is something the organization has NOT recognized as an issue but as a Network Administrator, is an major security issue.
Here is an example of what I am talking about.
A entry level engineer can open another engineers mailbox if they wanted. Again, I did NOT set permissions this way.
I am currently reading about the Exchange 2010 Server in order to properly figure everything out. However I need a quick fix right now. How can I set permissions so someone like a Entry Level Engineer can not open another engineers mailbox?
