Is it possible to recover email messages from the Microsoft Data folder?

I have a user in an Enterprise operation that was using Outlook for Mac.  She had a large exchange mailbox and a very large "on my computer" folder structure.  The Application became corrupt and I had to reinstall Outlook.  Database rebuild did not help.  I have a backup of the Microsoft user data folder.  Is it possible to extract the "On My Computer" Folders and emails from this database?  Many thanks!
