I had a user's BB show up with duplicate address book entries. I ran the BB procedure using the Desktop Manager to clear the address book, resync'd, duplicates were still there. Next I wiped the BB via the 10 wrong passwords method, resync'd, duplicates were still there. Finally I wiped the BB again, via the 10 password method, deleted/readded the user account from the BES (choosing the delete mail info option), resync'd, no more duplicates.
Can anyone provide some insight into what the actual problem is? Is this a ZCB bug?
