I'm using Garethp/php-ews package to manage Exchange data.
I'm able to read Calendar that other user shared with me, but unless they gave me write access on their Calendar (Under web client, I can add event), I'm not able to add events trough php.
I think I have to use
$calendar = $api->getCalendar();
$userCalendar = $calendar->pickCalendar($displayName);
If I'm right, how to get his $displayName ?
Thanks
I think I found a solution:
This script add event on a shared calendar.
