I'm creating calendar events as per following example : https://learn.microsoft.com/en-us/exchange/client-developer/web-service-reference/createitem-operation-calendar-item
I'm using PHP-EWS to achieve it. My code works fine. Although, I want to make the calendar items as read only. I do not see any documentation about it.
Has anyone achieved this?
Can someone direct me to the right direction. Many Thanks.
