This typically happens for old appointments that have become corrupted or were incorrectly created by a third-party application (for example, sync or CRM application).
Resolution

- Retry failed items (subjects will be logged).
- Review error logs to identify the offending calendar items.
- Fix the start/end date (i.e., open and save each calendar item).
