I am having a problem restoring pst files that I backed up from my Outlook 2007 file to my 2010 software. Previously in my 2007 Outlook, I had one list of folders for the email addresss I had. After installing 2010, I have two separate sets of folders shown in my email display. One shows my email address with the traditional folders, inbox, trash etc, and the other shows all of my folders from 2007 which is titled, Outlook Data files. I would like to find a way to merge these folders, so I can unclutter my display.
