So I was tasked with upgrading about 150 users from Office 2007 Pro Plus to Office 2010 Pro Plus. I thought no sweat, I can push the install (by the way pushing or manually performing install works)

Where I am finding problems are:

The Outlook loses the "address books" which some user have as many as 10 address books, which are located in "Contacts inside of multiple Public Folders" Can I find or export these Outlook Address Books?
I have to downgrade which brings other issues such as having to create a new Outlook Profile, once the profile is upgraded to 2010 I can't go back to 2007 and use that same profile.

As a result I'm kinda of scratching my head trying to figure out how to move forward. Any assistance would be greatly appreciated.
