Most likely you can't. How did you migrate your data? If you did an in place
upgrade of Office without taking care to migrate your data separately, your
profile is corrupt. Create a new one.

After migrating to office 2007 from Office 2003, the check box to "Show
folder as e-mail address book" is unavailable. How can I correct this?

Thanks, Mike
