Addressbook problem after sync with Microsoft Exchange

[yumin.shen]

I find once the contact in iphone is synced with Microsoft Exchange, programming on contact may fail with no error notification. It means when I try to set an email to an existing contact with custom label. The code execute corrrectly(&errror parameter will be null after operation) but the email is not added to that contact actually.
However if my code create a new contact and set an email with custom label it works. But I can't add an new email to that contact manually any more.
Any idea about it?

One issue is that once it syncs it changes the record_id, even though the documentation says that the number should stay unique.
