Hi,

I am trying to insert an Itemproperty in the Outlook Appointment item as
follows :

Outlook.ItemProperty olItemProperty = _olEvent.ItemProperties["MyKey"];

//create new property if the same doesn't exists
if (olItemProperty == null)
{
olItemProperty = _olEvent.ItemProperties.Add("MyKey"),
Microsoft.Office.Interop.Outlook.OlUserPropertyTyp e.olText, false, null);
}

Actually, the problem is that when i save the appointment, the ItemProperty
i added doesnt remain in the Item. It seems to get lost. Can anyone tell me
what could be the reason ?

I posted the same a Microsoft VSTO blogs where Sue Mosher told me that as
per "Ken Slovak", the item must be passed as using "ref" keyword. Why ?

Ken,
Can you please reply on this ? The same code is working on the other
machines i have. Is there any way to debug this problem ?
