BB Torch :: Merging Two Contact Lists?

I started in a new position not long ago with a BES Express server. First time BES admin, so go easy on me

I have a user who had a Bold 9700, which contained 5 address books all called Desktop. 3 of these were empty, one had 403 contacts and the other had 452 contacts. The one with 403 contacts sync'd up with Outlook no problem, however it seems as though whenever he added a contact directly to the device it went to the other list with 452. Blackberry Desktop can't seem to see these contacts to sync to the computer.

He was due a device upgrade, so we went to a Torch 9800. I backed up the data from his old device and restored it to the new one. Now I have 2 address books; one called Desktop with 403 items and the other called Unknown with 452 items. Again, the "Unknown" one can't be seen by Blackberry Desktop Software and won't sync to his PC.

All the fixes I've managed to find have involved deleting his lists on the device and resyncing from the Outlook client. This doesn't help me unfortunately, as he has hundreds of contacts on his device which don't exist in Outlook at all.

how I can either get the desktop software to see the "Unknown" list, or merge the two together.
