In 2007 it was easy and I am sure it must be easy in 2013 but I can't seem to find a way to check all mail going into a mailbox.
I have checked mailflow - delivery reports -- selected the mailbox and search... All I get is mail from the person to other people. I want to see all the messages they are getting from other people. I just need to know mailflow is working. The search pane results would be great if they included anything from other people. What am I missing?
The mail I am looking to find is not from anyone in our internal infrastructure so I can't just check that mailbox.
IE Mail box "Dave" -- How many messages has Dave received.
