When I tried to import ics file containing some events it got import successfully to my Outlook calendar. But when I tried to cancel/delete those events on Outlook by importing the ics-cancel file, it gives me the message "Could't import calendar. Try again later.Error message".
Error thrown on import cancelled ics file on Outlook Web
The ICS file containing events :-

I need help how to make the events cancelled in the outlook calendar ? Is there a specific format to make events cancelled in outlook? What is the correct way to cancel events so that they disappear in outlook calendar, like in Google Calendar? This works fine in Outlook Desktop app, I imported the normal ics file, after that I imported cancelled events ics file, I see it did not delete the event rather it stacked it in the same time slot, for example see the 'Meeting with Max Rob' it has been duplicated after importing the cancelled event ics file. Importing cancelled event ics after normal ics import on Outlook Desktop
When it didn't work on outlook web, I tried importing it in the Outlook Desktop app, it got imported but I saw it stacked the cancelled event. I expected after importing the cancelled ics file it would disappear the existing imported events from the calendar, like it does on Google calendar. How do I need to change my ICS, so it works properly? I saw various threads on stackoverflow, tried but none of them worked for Outlook web.
