outlook doesn't apply selected time zone on ToDo Tasks

Question

As we said, Outlook doesn't apply the selected time zone on ToDo Tasks. Local time is UTC+5:30 and we set a task on March 17 4 am. If we read the task out via MS Graph then we get we tasks with the startdate March 16 18:30:00 (UTC). If we use the selected time zone, the expected value supposed to be March 17 3 am. Thanks

Hi @Constantin Kwiatkowski

You should attach the request header of your target time zone when calling the graph API, otherwise it will return your task information in the default UTC time.

GET https://graph.microsoft.com/v1.0/me/todo/lists/{todoTaskListId}/tasks/{taskId}
Prefer: outlook.timezone="{your target time zone}"

Hope this helps.
