How to set ItemProperties (Microsoft.Office.Interop.Outlook.AppointmentItem.ItemProperties) for the Meeting request sent through Aspose.Email

Hi,

As per the documentation / forum discussions, for setting an custom ItemProperties for Outlook items, we need to add Headers to the Aspose.Email.Mail.MailItem.

But after setting the headers and sending it through the SmtpClient, when we receive the meeting in Outlook, we are not able to get the item properties.

Please let us know where can we find this or how can we set the ItemProperties
