KB14818-"Error encounter. Error code
I found one old contact causing the issue - email populated, email 2 blank, email 3 populated.
Funny things:
1) I have been USB syncing with 5.0.0.699 for awhile without seeing this issue and I have a Tour 9630 syncing to the same Address Book without issue.
2) I have not updated this contact in about 3+ months.
