Hi @Parth Kumar ,

You can use event-forward Graph API to forward calendar events to additional participants. Here is an example Graph API.

POST https://graph.microsoft.com/v1.0/me/events/{id}/forward  
Content-type: application/json  
  
{  
  "ToRecipients":[  
      {  
        "emailAddress": {  
          "address":"******@contoso.com"  
        }  
      },  
      {  
        "emailAddress": {  
          "address":"******@contoso.com"  
        }  
      }  
     ],  
  "Comment": "hope you can make this meeting."   
}

Hope this helps.

Hi @Parth Kumar ,

Thanks for confirming the suggested solution helps you, once the meeting is forwarded the original event will gets automatically updated with additional participants and organizer will be notified of the same.
If the original event is cancelled all participants including the new participants will get the cancellation.

Hope this helps.

I have used the same thing you shared, I am getting a blank response which means it is a success, but the event doesn't appear on the attendee calendar view. Attaching the screenshots below :

This evenonis of the organiser calendar and is not coming up with the attendee calendar.

Note: I don't want them to put in group, I just have their email ids of attendees

Hi @Parth Kumar ,

Can you check the original invite has allow forwarding option is checked and if the option is unchecked then the attendees cannot forward the invite to additional participants. Graph APIs forward call will be success status, but event will not be forwarded to participants.

Also, further..

You can use 2 different APIs to create an OnlineMeeting

user-post-events-as-an-online-meeting these are associated with event and thus can be forwarded using event-forward

post-onlinemeetings, this API creates a standalone meeting that is not associated with any event on the user's calendar; therefore, meetings created via this API will not show on the user's calendar

Can you provide detailed steps, how you created the OnlineMeeting and who is trying to forward the event is it organizer or attendee and what is the requested body used both the times.

I am using the post-onlinemeetings, so got the reason why it is not coming, but if we use the user-post-events-as-an-online-meeting, then how can I get the thread id and other controllable things which we can use in post-onlinemeetings?

Hi @Parth Kumar ,

Thanks for comments.

To get threadId, for a teams online meeting created using POST /me/event you can use Retrieve an online meeting by joinWebUrl.

GET /me/events/{event-id}, from the response captured the onlineMeeting/joinUrl, refer to below image.

GET /me/onlineMeetings?$filter=JoinWebUrl eq '{joinWebUrl}' use the onlineMeeting/joinUrl with {joinWebUrl}, refer to below image.

Hope this helps.
