AppointmentStore.MoveAppointmentAsync always throws an UnauthorizedAccessException

Question

Hi,

I wanted to extend my app to allow moving an existing appointment from one calendar to another.
I have read and write access to both calendars - they are only different calendars "categories" on my windows live account.

The "default" windows live calendar and a "business appointments" calendar, also on windows live.

A call to 'AppointmentStore.MoveAppointmentAsync' always throws an UnauthorizedAccessException but I DO HAVE access to both calendars (I can create, edit, delete appointments in them).

Exeception:

System.UnauthorizedAccessException occurred
  _HResult=-2147024891
  _message=Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
  HResult=-2147024891
  IsTransient=false
  Message=Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
  Source=Windows
  StackTrace:
       at Windows.ApplicationModel.Appointments.AppointmentStore.MoveAppointmentAsync(Appointment appointment, AppointmentCalendar destinationCalendar)
       at Week_View_Common.Appointment.AppointmentStoreFascade.<MoveToOtherCalendarAsync>d__1b.MoveNext()
  InnerException: null

Has anyone used this method successfully?

best regards,
Hannes

Hi Hannes - can you post a small sample app for testing?

hi,

yes, i will do so - unfortunately it's a bit more complicated then it should be since this forum does not allow to attach .zip files, so i could compress and update my project.

1. Get access to store:

var store = await AppointmentManager.RequestStoreAsync(AppointmentStoreAccessType.AllCalendarsReadOnly);

2. Query for calendars:

var calendars = await store.FindAppointmentCalendarsAsync(FindAppointmentCalendarsOptions.None);
var calendar = calendars.First();

3. Get appointments:

var appointments = await store.FindAppointmentsAsync(startDateInclusive, timeSpan, findAppointmentsOptions);
var appointment = appointments.First();

4. Instead of using the first entry, there could be an UI to select an appointment and a calendar.

5. Call the Move method

await store.MoveAppointmentAsync(appointment, calendar);

=> this call always throws the exception.
