Outlook add-in (auto-scheduler)

Hi, I'm writing an add-in for Outlook 2003 which takes the tasks from the task list and schedules them in to the calendar with respect to task priority. I have managed to sort the tasks by priority in the task list view via:

_Items olTasks = olFolderTask.Items; // MSO items collection in folder

olTasks.Sort("[Priority]", true); // sort items by Priority before reading

int nTasksCount = olTasks.Count;

for (int i = 0; i < nTasksCount; ++i)

try

if (i == 0) // Should be called first before iteration start

olItemTask = (_TaskItem)olTasks.GetFirst(); // First item in collection

else

olItemTask = (_TaskItem)olTasks.GetNext(); // Starts with second item in collection

if (olItemTask.Complete) // Task allredy completed

continue;

However, when the tasks are sent to the calendar they lose this prioritised order and appear in order of task name. Any ideas
