Disable the invitation mail to the participants while create a event through graph create event api

While create an event using the graph API. After create a calendar event, the participants who present in the event, they will receive an invitation mail to attend the events. Is there any way to block the invitation mail to the participants through Graph API.

        "dateTime": "2023-08-03T02:30:00"
    },
    "isReminderOn": true,
    "reminderMinutesBeforeStart": 15,
    "attendees": [
        {
            "type": "required",
            "EmailAddress": {
                "Address": "******@outlook.com",
                "Name": "******@outlook.com"
            }
        }
    ],
    "end": {
        "timeZone": "Etc/GMT",
        "dateTime": "2023-08-03T03:00:00"
    },
    "body": {
        "contentType": "Text",
        "content": "To test meetings b/w test1 and test 2"
    },

    "location": {

}

Answer 1

Not having the posibility to disable the invitations is very bad. Imagine a CRM with thousands of appointments. The admin wants to enable the integration with O365, so he wants all the CRM appointments to be hosted on Outlook. On the initial synchronization all participants (users, existing customers, leads) will receive an invitation for appointments that already happened! This is very bad. Please include an option to disable invitations.

Hi Hari,

Thanks for reaching out. It is not possible via Graph API to create a meeting without sending out events. You could however create a channel meeting in Teams which should not send out invitations to channel members.
