APIs under the /beta
version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.
This action allows the organizer of a meeting to send a cancellation message and cancel the event.
The action moves the event to the Deleted Items folder. The organizer can also cancel an occurrence of a recurring meeting by providing the occurrence event ID. An attendee calling this action gets an error (HTTP 400 Bad Request), with the following error message:
"Your request can't be completed. You need to be an organizer to cancel a meeting."
This action differs from Delete in that Cancel is available to only the organizer, and lets the organizer send a custom message to the attendees about the cancellation.
This API is available in the following national cloud deployments.
