2 clients of the BES are occasionally getting the following messages. Has anyone seen these before? I know in the past I have seen it once and the user noticed a calendar entry that didn't match up and that fixed it.

If this is the same thing how can I narrow down the messages/contacts/calendar entries that are causing the issues and how can I avoid this problem in the future?
