Configuration options on outlook.live.com mail account for Calendar Invitations Only visible on iPad

Configuration options on outlook.live.com website mail account for Calendar Invitations > “Control how invitations, responses, and notifications are handled”, not visible on desktop computer browsers. These options are visible only on iPad browser. 

This is not expected. I have tried it on multiple computers and different browsers. But the problem remains the same on all browsers and computers.

What is expected:

The configuration options for Calendar Invitations should be visible on desktop computer browser as is displayed on iPad browser.
