This issue can be resolved by taking manual action on these events. To do so, please follow the steps below:

1. Open your calendar in Microsoft Outlook.
2. Select “View by Category.” (Main Menu > View > Arrange By > Current View > By Category)
3. You’ll see a list of events (if the events are collapsed in categories, you can expand them by clicking the “+” sign). Using the icons to the left of each event, find events that have a “warning” icon (i.e. crossing swords), events that don’t have a start date or end date, or events which have an end date before the start date.
4. Double-click on each problematic event to resolve the problem or delete the problematic events.
