  • Launch Outlook on your iPhone.
  • Select the Calendar icon and then your account icon.
  • Uncheck calendars you prefer not to view.

By following these steps, you ensure that any changes made to your calendars—whether on your PC or iPhone—are instantly reflected across all your devices. This eliminates the need for manual resyncing after each update, making your Outlook calendar management seamless and efficient.
