I tested the above Graph API call in Microsoft Graph Explorer and POSTMAN, which works. So i dont think its issue with Graph API call. Just to isolate the issue, I would suggest you to test the code individually for tasks and events to see if it helps.
GraphClient, C# unable to fetch Appointments created in Outlook.
I am using GraphServiceClient v1.0. With OAuth token.
I have Calendars.ReadWrite, Calendars.ReadWrite.Shared, User.Read permissions.
I use Calendars.ReadWrite scope for this request.
I am able to create and get Events and Tasks(using default task list).
Where I am struggling is to get the Appointments created in Outlook.
All the events/tasks created programmatically can be retrieved, but not the outlook created Appointments. I tried with Events and CalendarView but both return same results.
Am I missing something, or need to hit a different end point?. Here is the code
var graphClient = new GraphServiceClient(baseUrl,
new DelegateAuthenticationProvider(async (requestMessage) =>
{
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", token);
})
));
var queryOptions = new System.Collections.Generic.List<Microsoft.Graph.QueryOption>()
{
new Microsoft.Graph.QueryOption("startDateTime", "2020-12-06T19:00:00-08:00"),
new Microsoft.Graph.QueryOption("endDateTime", "2020-12-07T19:00:00-08:00")
};
var calendarView = await graphClient.Me.CalendarView
.Request(queryOptions)
.GetAsync();
var meetingEvents = await graphClient.Me.Events
.Request()
.GetAsync();
var tasks = await graphClient.Me.Todo.Lists[taskListId].Tasks
.Request().Top(20)
.GetAsync();
// And I am combining both the results (meetingEvents, tasks) to obtain final list of entire tasks
Thanks in advance.
