Outlook – All-Day Events from another time zone do not display consistently

If I view an all-day event in my Outlook calendar that:

  • Was created in a different time zone
  • Goes for multiple days
  • Has all-day event ticked

The event will show as one day shorter than the actual event. The hover preview shows the same (incorrect) number of days. If I open the event, it displays correctly.

Please fix this inconsistency.
