Outlook 2010 - Multiple Address Books Imported from 2007 Visible but Not Accessible

[BradTinBC]

Hello,

I've recently migrated from XP / Office 2007 to Windows 7 / Office 2010. I copied my Outlook 2007 outlook.pst file, renaming it to username.pst.

Things work generally OK, except for one thing: I had 4 Contact Address Books in Outlook 2007, one named Contacts, the other 3 with names I provided. In Outlook 2010, when I click on Contacts, I can see these 4 Address Books (indented, under My Contacts), plus a new one "Suggested Contacts".

However, it seems I can't access any of the Address Books except for the one called "Contacts". For example, if I do: New Contact Group / Add Members / From Address Book, under the Address Book dropdown all I see is:
Contacts
Suggested Contacts
Contacts (Mobile)
Suggested Contact (Mobile)

So, how do I get my additional Address Books to be available?

Thanks for your help.

Found the answer, on superuser.com:

Try this: Right click the address book in question (under Contacts) > Properties
On the tab "Outlook address book" tick the box "Show this folder as an address book"
