Windows 10 mobile no function at all
It looks like the app is no longer working under Windows 10 .107 on lumia 950xl. No calender entry (vcs) is imported at all.
Outlook Calendar now supports built-in iCal import on Windows 10

I tried to open ics from google. I had meeting invite in google, I forwarded mail to other email. From the other email, I try to open the invite.ics, I see outlook open and then a black screen. Back button two times, I can then see the app with add new or open file.
I download the ics file to my device, try to use app to open the ics manually and it does the same thing, black screen
