Hi Sagi,
Check the example 3 of the below documentation to create recurring event using graph API
https://learn.microsoft.com/en-us/graph/api/user-post-events?view=graph-rest-1.0&tabs=http#example-3-create-a-recurring-event
As you said you are using the GRAPH APis directly to do the integration right?
So why not use the same to do a recurring meeting?
POST https://graph.microsoft.com/v1.0/me/events
"recurrence": { "pattern": { "type": "weekly", "interval": 1, "daysOfWeek": [ "Monday" ] }, "range": { "type": "endDate", "startDate": "2022-01-12", "endDate": "2022-03-31" } },
Not sure if you needed this or something else.
