Outlook Sync error

[bankerIT]

After updating a customized contact form, new contacts that I add appear in my contacts folder for a few moments and then disappear before my eyes. The error message in the Sync Issues folder is follows below. There was no change in the permissions when the form was updated and published. Any comments?
