I use [create event](https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/user_post_events) api to create an event object with "onlineMeetingUrl: <https://meet.lync.com/example/joyce/NLSD7Y62>" but the response of "onlineMeetingUrl" is null.

Is it a bug or is there any way to create a new event with 'onlineMeetingUrl'?

Here are my test steps.

Step 1. `POST /me/events`

```
{
    "@odata.etag": "W/\"BfXylo4WykyAenTZICXL5AAApUQ11g==\"",
    "id": "AAMkADVmMzE2MjY0LTZkOGYtNGI4MS1iNWMxLTljYzg3MWY5MWQxMQBGAAAAAABZMfR36TVMQ6yunaqZPvVRBwAF9fKWjhbKTIB6dNkgJcvkAAAAAAENAAAF9fKWjhbKTIB6dNkgJcvkAAClFy2jAAA=",

    "onlineMeetingUrl": "https://meet.lync.com/example/joyce/NLSD7Y62",
    "responseStatus": {
        "response": "organizer",
        "time": "0001-01-01T00:00:00Z"
    },
    "body": {
        "contentType": "html",
        "content": "Join online meeting"
    },
    "start": {
        "dateTime": "2018-03-08T00:00:00.0000000",
        "timeZone": "UTC"
    },
    "end": {
        "dateTime": "2018-03-08T00:30:00.0000000",
        "timeZone": "UTC"
    },
    "location": {
        "displayName": "Online meeting"
    },
    "recurrence": null,
    "attendees": [],
    "organizer": {
        "emailAddress": {
            "name": "Joyce",
            "address": "joyce@example.com"
        }
    }
}

```

Step 2. The onlineMeetingUrl in the response event object is null.

```
{
    ...
    "onlineMeetingUrl": null,
    ...
}

```
