A user created an address book with no name (null). Upon opening GroupWise as the user, an error message is received "The folder name: " is invalid. Please try again."

The trouble is that it continually pops up each time you try to access the address book to change it. I have been looking for a back door to access this address book so I can delete it or rename it. I have looked in iManager and ConsoleOne with no luck.

Is there any help out there?
