I'm using Outlook 2007 with Exchange 2007.

I have the global address list, my address book as well as three public
folders configured as address books all recently imported from a legacy mail
system.

I am attempting to sort it by Last Name, First name.

To date, I have the Last name sort configured in the 'Address Book' section
where I selected sort on 'File As'.

I've discovered that all 5000+ contacts are 'Filed As' First Last
Is there any way to mass edit the contacts so they are all 'Filed As' Last,
First instead of the default First Last
