Example

Request

The following example gets within the specified time range the occurrences and exceptions of an event which is the master event of a recurring series.

GET https://graph.microsoft.com/beta/me/events/AAMkAGUzYRgWAAA=/instances?startDateTime=2019-04-08T09:00:00.0000000&endDateTime=2019-04-30T09:00:00.0000000&$select=subject,bodyPreview,seriesMasterId,type,recurrence,start,end

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.
