New Outlook not adding Events or Calendars via .ics file

Recently, Microsoft updated the Windows version of Outlook to what is now called Outlook (New) instead of Outlook (Classic). Unfortunately, the new Outlook has a known issue where it cannot open or load event and calendar .ics files, unlike the classic version.

Since this is a limitation within Microsoft's tool, we are unable to provide a direct fix. However, there are some workarounds available.

Workaround: Use Outlook.com or Office 365

The easiest solution is to use the Outlook.com Add to Calendar option (for personal Microsoft accounts) or the Office 365 option (for work/school Microsoft accounts). When you add an event or subscribe to a calendar through one of these online options, your changes will automatically sync to your desktop version of Outlook.
