In GroupWise mail client, we can set the return notification by creating a new message, select "Send Option", select "Status Tracking", then in the Return notification section set the action for when opened.

I tried to implement this using SOAP(C#), but I didn't find a way to set it on a GroupWise.Mail item.

My question is can this be done using SOAP?
If the answer is Yes, then how to set it in C#?
