I have this same problem. outlook 2007 installed on a vista home premium OS, used for personal use on a POP3 account.

I have done as you all have suggested, but here is where I run into trouble:

1) Control Panel
2) Mail
3) Email Accounts
4) Address Books
5) There is only one address book, "Outlook Address Book" Type MAPI.

I cannot:
A) Delete it
B) change its name
C) add an additional Outlook Address Book

I have tried reloading the pst file, I have tried reinstalling Office, nothing works.
