iMac Hard drive crashed – recovering Outlook 2011 emails

My iMac 520 hard drive crashed. I was able to get most of the data off onto a new 1 tb drive. I've reinstalled Outlook 2011 and copied the email folders out of the identity folder. I see my email folders but none of my incoming emails. I do see all of my SENT emails. When I look at the Messages folder on my backup disk they appear in multiple folders 0-4K but now on my mac I only see folder OK. I've tried copying the folders individually and when it rebuilds, the emails do not appear in the folders. When I click on one of my messages on the back up drive, I get the following pop-up "Outlook cannot open the file because it is not associated with the default identity." PLEASE HELP?
