Simple - and works
Every time I get a calendar invite from someone using Outlook on a PC, my Mac can’t read it…. So I try a Winmail app…. Without success (in some cases, after purchasing “premium” version… In frustration, I tried Letter Opener, and bang! It worked… dragged the file into Letter Opening which immediately created a calendar appointment. Simple task… simple solution….
