Send Mail/Task/Appointment with Redemption - outlook

Question

I am trying to programmatically send a Mail/Task/Appointment to a user and I have the problem, that every time I send them the first one will get stuck in my outbox... It seems that the first one sent to Outlook has no/looses its sent-date and will stay forever in my outbox.
Here is the code for example "sending a task notification"
using (MapiSession session = new MapiSession())
{
var item = session.CreateItem(Outlook.OlItemType.olTaskItem) as RDOTaskItem;
[..]
try
{
item.Subject = "SUBJECT";
item.Body = "BODY;
item.StartDate = DateTime.Now;
item.DueDate = DateTime.Now;
item.Recipients.Add("test#mail.com");
item.Recipients.Add("test2#mail.com");
item.Recipients.ResolveAll();
item.Assign();
item.Save();
item.Send();
}
[..]
}
Thanks in advance.

Answer 1

So I am not really shure what is the problem so far...
If all receivers are other persons then myself this should work...
Here is my code for sendig a TaskItem
private void NotifyByTask(OutlookNotificationTypes notificationType)
{
Application app = new Application();
var item = app.CreateItem(OlItemType.olTaskItem) as TaskItem;
try
{
item.Subject = this.Subject;
item.Body = this.Body;
if (this.Start != DateTime.MinValue)
{
item.StartDate = this.Start;
item.ReminderSet = true;
item.ReminderPlaySound = true;
item.ReminderTime = this.Start.AddMinutes(-5);
}
if (this.End != DateTime.MinValue)
{
item.DueDate = this.End;
}
item.PercentComplete = this.PercentComplete;
StringBuilder categories = new StringBuilder();
foreach (String category in this.Categories)
{
categories.Append(category);
}
item.Categories = categories.ToString();
bool sendingToMyself = false;
if (this.NotificationType == OutlookNotificationTypes.TaskRequest)
{
// this will add all recipients and checks if Receiver is yourself
sendingToMyself = item.AddRecipients(this.Recipients, OlMailRecipientType.olTo);
}
if (this.NotificationType == OutlookNotificationTypes.TaskRequest
&& (!sendingToMyself))
{
item.Recipients.ResolveAll();
item.Assign();
item.Save();
item.Send();
}
else
{
item.Save();
//insert element
if (this.ItemSaved != null)
{
Microsoft.Office.Interop.Outlook.MAPIFolder folder =
item.Parent as Microsoft.Office.Interop.Outlook.MAPIFolder;
if (folder != null)
{
try
{
String storeId = folder.StoreID;
String entryId = item.EntryID;
this.ItemSaved(storeId, entryId);
}
finally
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(folder);
}
}
}
}
}
finally
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(item);
}
}
