I've exported 10 GB worth of my emails using the Export utility on my Outlook 2007 (PC). Now as I imported the .PST file on my Outlook 2011 (Mac), most and all of the data is imported; however some folders are missing the emails (no big deal, I can copy them)... though the main problem is that the 'Sender' is not showing up any longer in emails older than 11/125/2012. Meaning it does not show who the sender is; it simply shows To, Date, Subject, but not Sender.
