That file is called PIM.vol on the 6700. I think if you rename that to PIM.old and soft reset the 6700, it will make a new, empty one. Not exactly sure, though, but vaguely remember something like that. Search around or google to be sure or maybe someone else can verify. So, theoretically, if you sync with PC Outlook (Outlook.pst where all your contacts are) they should go to Mobile Outlook (PIM.vol). But sometimes, they get erased from both places so make sure you back up your "good" .pst file. Depends on what it syncs/replaces with, the empty file or full file. You can't really specify anymore what device to override with like you used to. That was MS's "improvement".

Maybe the workaround is to have atleast one contact in the empty 6700 contacts that will trigger AS to make them the same. So sync what you can from the "bad" 6700 file to the PC (calendar, tasks). Then sync everything (contacts, calendar, and tasks) to the "new" 6700 file. That should get you back with any luck.
